Sifat distributif dari 12 x (10 + 24) yang benar adalah ....
Correct Answer
C. ( 12 x 10 ) + ( 12 x 24 )
Explanation
The correct answer is ( 12 x 10 ) + ( 12 x 24 ). This is because the distributive property states that when multiplying a number by a sum, you can multiply each term of the sum individually and then add the results. In this case, 12 is multiplied by both 10 and 24 separately, and then the results are added together.
2.
( 12 + 15 ) + 25 = 12 + ( 15 + 25 )
Sifat operasi hitung bilangan di atas adalah ....
Correct Answer
B. Asosiatif
Explanation
The expression (12 + 15) + 25 is equal to 27 + 25, which simplifies to 52. On the other hand, 12 + (15 + 25) is equal to 12 + 40, which also simplifies to 52. This shows that the order in which the addition is performed does not affect the final result. Therefore, the operation of addition in this expression is associative.
3.
Semua bilangan yang ditambahkan 0 maka hasilnya adalah ....
Correct Answer
A. Tetap bilangan itu sendiri
Explanation
When any number is added to 0, the result will always be the number itself. This is because the addition of 0 does not change the value of the number being added. In other words, adding 0 does not affect the original number in any way. Therefore, the correct answer is "Tetap bilangan itu sendiri" which translates to "The number remains the same."

Urutan bilangan di bawah ini yang benar dari yang terbersar adalah ....
Correct Answer
D. 18.476 – 14.876 – 14.768 – 14.678
Explanation
The correct answer is 18.476 – 14.876 – 14.768 – 14.678. This is the correct order from largest to smallest because the first number, 18.476, is the largest among all the given numbers. Then, we compare the second digits after the decimal point, which are all 8. Since 14.876 has the highest third digit after the decimal point, it comes next. Then, we compare the third digits after the decimal point, which are all 7. Among these, 14.768 has the highest fourth digit after the decimal point, so it comes after 14.876. Finally, 14.678 is the smallest number among all the given options, so it comes last.

Selisih nilai angka 7 dan 5 pada bilangan 759.034 adalah ....
Correct Answer
D. 650.000
Explanation
The question asks for the difference between the numbers 7 and 5 in the number 759,034. To find this difference, we subtract 5 from 7, which equals 2. However, the answer is given as 650,000. This suggests that the question is asking for the difference in terms of place value, with the 7 representing 700,000 and the 5 representing 5,000. Subtracting 5,000 from 700,000 gives us 695,000, which is closest to the given answer of 650,000.
