we know that

A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers

case a) We round the number to the nearest hundred

so


196 Round up is equal to
200


482 Round up is equal to
500

Find the estimate sum


200+500=700

case b) We round the number to the nearest tens

so


196 Round up is equal to
200


482 Round down is equal to
480

Find the estimate sum


200+480=680
