Q: <font color=red> Estimate:  0.5162 + 9.436 + 350.12 + 800.25 + 25.78 </font>


A:



First, let's round each number to the whole number:


0.5162 rounds to 1,
9.436 rounds to 9
350.12 rounds to 350
800.25 rounds to 800
25.78 rounds to 26



So the expression simplifies to 

1 + 9 + 350 + 800 + 26



Add 1 and 9 to get 10. Add 800 and 26 to get 826


10 + 350 + 826


Add 10 to 350 to get 360


360 + 826



Now add up the remaining numbers


1186


So the estimated answer is 1,186



Note: the true answer is 1,186.1022
