Question

Julia rounded to the nearest ten to estimate the difference between two numbers. The estimated difference was 10. What are four pairs of numbers she might have sustractrd?

Answer 1

To round off to 10, the difference should range from 5 to 14. If the difference between two numbers is from 5 to 14, they all are rounded to 10.

Example:

$18-9=9$ (near to 10)

$26-15=11$

$46-39=7$

$50-42=8$
