Question

Estimate the sum to nearest ten$.$

$673+251$

Answer 1

We want to find out the given sum $673+251$

In $673$ the unit digit is $3$$,$ unchanged the ten's digit and replace the unit digit by $0$

nearest ten to $673$ is $=670$

In $251$ the unit digit is $1$$,$ unchanged the ten's digit and replace the unit digit by $0$

nearest ten to $251$ is $=250$

Required sum $=670+250$

$=920$

Hence$,$ the sum to nearest ten is $920$
