25 % jika diubah ke bentuk pecahan biasa menjadi ....
- A.
2⁄5
- B.
1⁄5
- C.
1⁄2
- D.
1⁄4
Correct Answer
D. 1⁄4Explanation
The fraction 1/4 is equivalent to 25% when expressed as a common fraction. This is because 25% can be written as 25/100, which can be simplified to 1/4 by dividing both the numerator and denominator by their greatest common divisor, which is 25. Therefore, the correct answer is 1/4.Rate this question:

- A.
2⁄20
- B.
1⁄10
- C.
10⁄100
- D.
10⁄20
Correct Answer
D. 10⁄20Explanation
The fraction 10/20 is not equivalent to 10% because to convert a fraction to a percentage, you need to divide the numerator by the denominator and multiply by 100. In this case, 10 divided by 20 is 0.5, and when multiplied by 100, it becomes 50%. Therefore, 10/20 is not equal to 10%.Rate this question:

Pecahan biasa dari 0,02 adalah ....
- A.
2⁄4
- B.
2⁄10
- C.
1⁄50
- D.
2⁄1000
Correct Answer
C. 1⁄50Explanation
The correct answer is 1/50. When we have a fraction, the denominator represents the total number of equal parts into which the whole is divided, and the numerator represents the number of those equal parts that we have. In this case, the whole is 0.02, and we need to find a fraction that represents a part of it. 1/50 means that we have 1 out of 50 equal parts of 0.02.Rate this question:

Andi mempunyai tali sepanjang 1⁄4 meter dan Ali mempunyai tali sepanjang 1⁄3 meter. Maka jumlah tali Andi dan Ali jika ditambahkan menjadi ....
- A.
7⁄12
- B.
2⁄12
- C.
2⁄7
- D.
7⁄7
Correct Answer
A. 7⁄12Explanation
Andi memiliki tali sepanjang 1/4 meter dan Ali memiliki tali sepanjang 1/3 meter. Untuk menjumlahkan panjang tali Andi dan Ali, kita perlu menemukan persamaan pecahan dengan penyebut yang sama. Kita dapat melakukannya dengan mengalikan penyebut dari masing-masing pecahan. Jika kita mengalikan 1/4 dengan 3/3, maka kita akan mendapatkan 3/12. Jika kita mengalikan 1/3 dengan 4/4, maka kita akan mendapatkan 4/12. Jadi, jumlah tali Andi dan Ali adalah 3/12 + 4/12 = 7/12.Rate this question:

- C.
16⁄15
- D.
16⁄45
Correct Answer
A. 2⁄15Explanation
When subtracting fractions, we need to have a common denominator. In this case, the fractions already have a common denominator of 15.
So, we can subtract the numerators directly: 9/15 - 3/15 - 4/15 = (9 - 3 - 4)/15 = 2/15.
Therefore, the result of the subtraction operation is 2/15.Rate this question:

- D.
7⁄20
Correct Answer
D. 7⁄20Explanation
The given question asks to subtract two fractions, 3/4 and 2/5. To subtract fractions, we need to have a common denominator. In this case, the common denominator is 20. So, we convert 3/4 to 15/20 and 2/5 to 8/20. Subtracting these fractions gives us 15/20 - 8/20 = 7/20. Therefore, the correct answer is 7/20.Rate this question:

- B.
2⁄8
- C.
2⁄10
- D.
7⁄10
Correct Answer
C. 2⁄10Explanation
Diska awalnya memiliki pita sepanjang 1/2 meter. Kemudian ia menggunakan pita sepanjang 3/10 meter. Untuk mencari sisa pita Diska, kita perlu mengurangi panjang pita yang digunakan dari panjang pita awal. Jadi, sisa pita Diska adalah 1/2 - 3/10 = 5/10 - 3/10 = 2/10. Oleh karena itu, jawaban yang benar adalah 2/10.Rate this question:

7⁄8 x 3⁄4 = .... Hasil dari operasi perkalian pecahan di atas adalah ....
- A.
21⁄24
- B.
28⁄24
- C.
24⁄21
- D.
24⁄28
Correct Answer
A. 21⁄24Explanation
When multiplying fractions, you simply multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator. In this case, 7/8 multiplied by 3/4 equals (7*3)/(8*4) which simplifies to 21/32. However, since the answer choices are given in the form of simplified fractions, we can further simplify 21/32 by dividing both the numerator and denominator by their greatest common divisor, which is 3. Therefore, 21/32 simplifies to 7/8, which matches the given answer of 21/24.Rate this question:

- C.
3⁄10
- D.
9⁄10
Correct Answer
D. 9⁄10Explanation
The given question asks for the result of dividing the fraction 3/10 by the fraction 1/3. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/3 is 3/1. So, we can rewrite the division as 3/10 multiplied by 3/1. Multiplying the numerators (3 * 3) gives 9, and multiplying the denominators (10 * 1) gives 10. Therefore, the result of the division is 9/10.Rate this question:

Pak Panji membeli buah jeruk seberat 1 Kg. Buah tersebut diberikan kepada anak-naknya. 10 % buahnya diberikan kepada Santi, 0,5 diberikan kepada Budi dan 3⁄10 kg diberikan kepada Sinta. Dan Sisanya diberikan kepada Rani. Jadi siapakah yang mendapat buah jeruk paling banyak?
- A.
Santi
- B.
Budi
- C.
Sinta
- D.
Rani
Correct Answer
B. BudiExplanation
Budi received the most oranges because he received 0.5 kg of oranges, while Santi received 10% of the oranges and Sinta received 3/10 kg of the oranges. Since 0.5 kg is a larger amount than 10% or 3/10 kg, Budi received the most oranges.Rate this question:

Perbandingan siswa laki dan perempuan dalam kelas adalah 5 : 7. Jika siswa laki-laki dalam kelas adalah 15 siswa, maka siswa perempuan berjumlah ....
- A.
21 siswa
- B.
20 siswa
- C.
28 siswa
- D.
18 siswa
Correct Answer
A. 21 siswaExplanation
Given that the ratio of male to female students in the class is 5:7, and there are 15 male students, we can calculate the number of female students by setting up a proportion.
Let x represent the number of female students.
We can set up the proportion:
5/7 = 15/x
Cross-multiplying, we get:
5x = 7 * 15
Simplifying, we have:
5x = 105
Dividing both sides by 5, we find:
x = 21
Therefore, the number of female students in the class is 21.Rate this question:

Correct Answer
C. 4 : 7Explanation
The ratio between the number of male students and female students in the class is 4:7. This can be determined by dividing the number of male students (12) by the number of female students (21). Simplifying the ratio gives us 4:7.Rate this question:

Correct Answer
C. 1 : 3Explanation
The correct answer is 1:3 because the ratio of the number of pencils Sinta has to the number of pencils Rini has is 1:3. Sinta has 7 pencils and Rini has 21 pencils, which can be simplified to 1:3 by dividing both numbers by 7.Rate this question:

Jarak desaa A dan desa B adalah 1500 meter. Pada peta jarak desa A dan B adalah 3 cm. Jadi skala peta tersebut adalah
- A.
1 : 3
- B.
1 : 1500
- C.
1 : 1000
- D.
1 : 500
Correct Answer
D. 1 : 500Explanation
The correct answer is 1 : 500. This is because the scale of the map is determined by the ratio of the distance on the map to the actual distance on the ground. In this case, 3 cm on the map represents 1500 meters in reality. To find the scale, we divide the actual distance by the distance on the map: 1500 meters / 3 cm = 500. Therefore, the scale of the map is 1 : 500.Rate this question:

Jarak antara kota X dan Z pada peta adalah 8 cm. Jika skala yang dimiliki peta tersebut adalah 1 : 200.000, maka jarak sebenarnya antara kota X dan Z adalah ....
- A.
1.600.000 m
- B.
16 km
- C.
160 km
- D.
1.600 cm
Correct Answer
B. 16 kmExplanation
The distance between city X and Z on the map is 8 cm. The scale of the map is 1:200,000. This means that 1 cm on the map represents 200,000 cm in real life. To find the actual distance between the two cities, we need to multiply the distance on the map by the scale factor. Therefore, 8 cm x 200,000 cm = 1,600,000 cm. Since we want the answer in kilometers, we need to convert cm to km by dividing by 100,000. Therefore, 1,600,000 cm / 100,000 = 16 km.Rate this question:

Jika jarak rumah Nabila dan rumah Siska adalah 800 meter. Di dalam peta yang mempunyai skala 1 : 40.000. Maka jarak rumah Nabila dan rumah Siska adalah ....
- A.
2 cm
- B.
4 cm
- C.
6 cm
- D.
8 cm
Correct Answer
A. 2 cmExplanation
The scale of the map is 1:40,000, which means that 1 cm on the map represents 40,000 cm in reality. Since the distance between Nabila's house and Siska's house is 800 meters, we need to convert this distance to centimeters. 800 meters is equal to 80,000 centimeters. Since 1 cm on the map represents 40,000 cm in reality, 80,000 cm will be represented by 2 cm on the map. Therefore, the correct answer is 2 cm.Rate this question:
