Question

Estimate the difference by rounding off the number to the nearest hundreds:$900-675$

Answer 1

Step 1. Rounding off the numbers to the nearest hundred.

• $900$ is already in the hundred form.
• And $675$ lies between $600$ and $700$

Since $675$ is nearest to $700$ than to $600$.

Therefore $675$ rounded off to the nearest hundred as $700$.

Step 2.Find sum

$900-700=200$

Hence the difference by rounding off the number $900-675$ to the nearest hundreds is $200$
