    • 25

    • 28

    • 35

    Correct Answer
    A. 35
    Explanation
    The given expression can be simplified by first evaluating the parentheses. 8-2 equals 6. Then, adding 15 to 6 gives us 21. Finally, dividing 120 by 21 equals 5.714. Since none of the answer choices match this result, the correct answer is not available.

    Rate this question:

  • 3. 

    The total cost of 8 schoolbags is Rp192.000,00. Find the total cost of 5 similar schoolbags.

    • Rp100.000,00

    • Rp120.000,00

    • Rp160.000,00

    • Rp220.000,00

    Correct Answer
    A. Rp120.000,00
    Explanation
    If the total cost of 8 schoolbags is Rp192.000,00, we can find the cost of 1 schoolbag by dividing the total cost by the number of schoolbags. So, the cost of 1 schoolbag is Rp192.000,00 / 8 = Rp24.000,00. To find the cost of 5 similar schoolbags, we multiply the cost of 1 schoolbag by 5. Therefore, the total cost of 5 similar schoolbags is Rp24.000,00 * 5 = Rp120.000,00.

    Zero is a natural number. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Zero is not considered a natural number. Natural numbers are typically defined as the positive integers starting from 1. Zero, on the other hand, represents the absence or lack of quantity, and is not considered a positive integer. Therefore, the statement that zero is a natural number is false.

    Explanation
    The number '7' belongs to the category of integers and natural numbers. Integers are whole numbers that include both positive and negative numbers, and natural numbers are positive whole numbers. Since '7' is a positive whole number and not a fraction or decimal, it falls under both classifications.
