Bentuk paling sederhana dari pecahan 75⁄100 adalah ....
Correct Answer
D. 3⁄4
Explanation
The simplest form of a fraction is when the numerator and denominator do not have any common factors other than 1. In this case, both 75 and 100 can be divided by 25. When we divide 75 by 25, we get 3, and when we divide 100 by 25, we get 4. Therefore, the simplest form of the fraction 75/100 is 3/4.

Pecahan 2⁄4 , 1⁄5 , 3⁄9 dan 25⁄100 jika diurutkan dari yang paling kecil adalah ....
Correct Answer
A. 1⁄5 , 25⁄100 , 3⁄9 , 2⁄4
Explanation
The fractions are being sorted from smallest to largest. The fraction 1/5 is the smallest because the numerator is the smallest among all the fractions. Next is 25/100, which is equivalent to 1/4 and is larger than 1/5. Then comes 3/9, which is equivalent to 1/3 and is larger than both 1/5 and 1/4. Finally, 2/4 is the largest fraction because it is equivalent to 1/2 and has the largest numerator among all the fractions.

Pak Bayu memiliki lahan yang luasnya 200 m². Lahan Pak Bayu tersebut yang ditanami jagung adalah 3⁄4 bagian. Jadi lahan yang ditanami padi adalah seluas ....
Correct Answer
C. 150 m²
Explanation
Since the total area of Pak Bayu's land is 200 m² and 3/4 of it is planted with corn, we can calculate the area planted with corn by multiplying 200 m² by 3/4, which equals 150 m². Therefore, the area planted with rice would be the remaining area, which is also 150 m².

Bagus membeli 3⁄4 Kg Salak , Rina membeli 1 2⁄5 Kg jeruk dan Andre membeli 2 1⁄2 Kg manggi. Jumlah berat buah yang mereka bertiga beli adalah ....
Correct Answer
C. 4 13⁄20
Explanation
The question asks for the total weight of the fruits that Bagus, Rina, and Andre bought. To find the total weight, we need to add the weights of the fruits together. Bagus bought 3/4 kg of Salak, Rina bought 1 2/5 kg of jeruk, and Andre bought 2 1/2 kg of manggi. To add these fractions and mixed numbers, we need to find a common denominator. The common denominator for 4, 5, and 2 is 20. Converting the fractions to have a denominator of 20, we get 15/20 for Bagus, 8/20 for Rina, and 41/20 for Andre. Adding these together, we get 64/20 which simplifies to 3 4/20 or 3 1/5. Therefore, the correct answer is 4 13/20.

Hasil dari 1⁄2 x 4⁄10 : 3⁄8 = ....
Correct Answer
A. 8⁄15
Explanation
To find the solution to this expression, we need to follow the order of operations. First, we simplify the division of fractions by multiplying the first fraction by the reciprocal of the second fraction. So, 1/2 x 4/10 becomes 1/2 x 10/4. Next, we simplify this multiplication by canceling out the common factors between the numerators and denominators. In this case, we can cancel out the factor of 2. Thus, we are left with 1/1 x 5/4. Finally, we multiply the numerators and denominators together to get the final answer of 5/4, which can be simplified to 8/15.

Umur Yudi adalah 25 tahun, sedangkan umur Sintia adalah 4⁄5 umur Yudi. Jadi selisih umur Sintia dan Yudi adalah ....
Correct Answer
B. 5 tahun
Explanation
The age difference between Sintia and Yudi can be found by calculating 4/5 of Yudi's age. Since Yudi's age is 25, 4/5 of 25 is 20. Therefore, the age difference between Sintia and Yudi is 20.

Titik koordinat (4,6) jika diceminkan terhadap sumbu Y maka akan berada pada titik koordinat ....
Correct Answer
D. (-4,6)
Explanation
When a point is reflected across the y-axis, the x-coordinate remains the same but the sign changes. In this case, the original point is (4,6), and when reflected across the y-axis, the x-coordinate becomes -4 while the y-coordinate remains the same at 6. Therefore, the reflected point is (-4,6).
25.
Titik koordinat (10,3) jika dicerminkan terhadap sumbu X maka akan berada pada titik koordinat ....
Correct Answer
A. (10,-3)
Explanation
When a point is reflected across the x-axis, the x-coordinate remains the same, but the y-coordinate changes sign. In this case, the point (10,3) is reflected across the x-axis, so the x-coordinate remains 10, but the y-coordinate changes sign to -3. Therefore, the reflected point will be (10,-3).
