Question

Which of the following expressions is NOT equivalent to the following?

The image shows a long division problem. The dividend is 80, the divisor is 10.

Answer 1

When dividing by 10, we move the decimal point one place to the left. The expression that is NOT equivalent is 80 × 10 = 800.

Step-by-step explanation:

When dividing by 10, we move the decimal point one place to the left.

In this case, the dividend is 80, so dividing by 10 gives us 8. Therefore, the equivalent expression is 8.

Let's check the given options:

80 ÷ 10 = 8 (equivalent)

80 × 10 = 800 (not equivalent)

80 ÷ 100 = 0.8 (not equivalent)

80 × 100 = 8000 (not equivalent)

From the options, the expression that is NOT equivalent is 80 × 10 = 800.
