Question

Estimate 15.870 + 6.77 by first rounding each number to the nearest tenth​

Answer 1

Answer:

I think it is 22.7

Step-by-step explanation:

First take your 15.870 and round it to the nearest tenth to get 15.9 because of the 7. Then take 6.77 and do the same, and you get 6.8. Add these two numbers 15.9+6.8 and you get 22.7.
