Answer:
A little less than 5.
Explanation:
An estimate means you should be able to do it in your head.
400/80 = 5 So the answer should be about 5
Can we get it a little closer? Maybe.
Divide 375 in your head by 25. It's about 15
Divide 80 by 25 which is about 3.2
15/3.2 It's under 5. but not by much. Only now can you use a calculator. The rounded answer is 4.6
