Question

Estimate the sum by rounding off to the nearest hundred: 507+ 315​

Answer 1

Answer:

507 = 500

507 = 500315 = 300

507 = 500315 = 300300 + 500 = 800

Step-by-step explanation:

when we round off 507 to the nearest hundred as next to 5 it is 0 which is smaller than 5 so will change to 0 and the onea place will also change to 0. So the answer will be 500.

when we round off 315 to the nearest hundred as next to 3 it is 1 which is smaller than 5 so will change to 0 and the onea place will also change to 0. So the answer will be 300.

So , Now we will add the estimated numbers which are 300 and 500.

the answer will be 300 + 500 = 800
