Question

Which expression is NOT equivalent to 125.78 ÷ 1.23?

A. 12,578 ÷ 123

B. 1,257.8 ÷ 12.3

C. 1.2578 ÷ 12.3

D. 12.578 ÷ 0.123

Answer 1

Choice C.

Explanation:

For an expression to be equivalent you need to multiply or divide the 2 numbers in the original expression by the same number.

For example A is equivalent because both 125.78 and 1.23 have been multiplied by 100.

The odd one out is C because 125.78 has been divided by 100 but 1.23 has been multiplied by 10.
