Question

Estimate the difference to the nearest ten$.$

$67-52$

Answer 1

We want to find out the given difference $67-52$

In $67$ the unit digit is $7$$,$ increase the ten's digit by $1$ and replace the unit digit by $0$

nearest ten to $67$ is $=70$

In $52$ the unit digit is $2$$,$ unchanged the ten's digit and replace the unit digit by $0$

nearest ten to $52$ is $=50$

Required difference $=70-50$

$=20$

Hence$,$ the difference to the nearest ten is $20$
