Question

Estimate the sum by rounding off the number to the nearest hundreds:$587+182$

Answer 1

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

• As $587$ lies between $500$ and $600$

Since $587$ is nearest to $600$ than to $500$.

Therefore $587$ rounded off to the nearest hundred as $600$.

• Also $182$ lies between $100$ and $200$

Since $182$ is nearest to $200$ than to $100$.

Therefore $182$ rounded off to the nearest hundred as $200$.

Step 2.Find sum

$600+200=800$

Hence the sum by rounding off the number $587+182$ to the nearest hundreds is $800$
