Answer 1

A. 8637=8640
B. 11289=11290
C. 28946790
D. 7604=7600

Answer 2

To round off to nearest ten, what you gotta do is that you see the last digit. If it is less than 5, then take the lesser ten. And if equal to or more than 5, then the bigger ten

Here,

1. 3650 + 4980 = 8630
2. 9280 + 2010 = 11290
3. 28946790
4. 5380 + 2220 = 7600

A question for you now. What would be 324+ 342?
