Question

What is the best estimate for the answer to 382.24 – 297.28?

A.
85.1

B.
85

C.
84.9

D.
80

Answer 1

382.24-297.28= 84.96
Answer: B 85
To round a number it must be 5 or higher so since the nine in .9 is higher than five it raises the number to 85. And there are no numbers after that. That is the rule so it goes for any other ones too like, 100th or 1000th.

Answer 2

B,
the exact answer is 84.96, so most likely rounded,

RULES:
5 or above, shove it up.
4 or below, leave it.

9 is higher than 5, obviously.

So, B is the answer.
