\frac{1}{2} x-4<3 \quad\{7 \leq 3+5
Answer (3)
they need a common denominator. so the common denominator is 8. so multiply the 3 and the 4 each by 2. so then you get 6/8. then subtract 1/8 from 6/8. so it looks like 6/8-1/8 and you'll get an answer of 5/8.
Answer: .6

To estimate 4 3 − 8 1 , we convert 4 3 to have a common denominator of 8, resulting in 8 6 . After subtracting 8 1 from 8 6 , we get 8 5 left.
