Question

What is the best estimate for the value of the expression? (34/8 - 16/3) - 14/9

Answer 1

You want an estimate, not an actual answer. But just in case you think that way, the actual answer is 34/8 - 16/3 - 14/9 = -2 23/36

34/8 = about 4 3/4

16/3 = about 5 1/3

14/9 i= about 1 5/9

So the answer is about 5 - 5 - 1 1/2 which is about (- 1 1/2) That's your answer. Remember you are estimating. I don't know that you can get it much closer without using a calculator.
