Well, let's turn those numbers into a fraction. The number 3 can be written as 3/1 since any number can be written as itself over 1. So, 3 is the same as 3/1. And for 7 and 8, they can be written as 7/1 and 8/1 respectively. So, 3, 7, and 8 can be written as 3/1, 7/1, and 8/1 when expressed as fractions.
It is 31/8.

To rename a mixed number to a fraction, you multiply the number outside the fraction by the denominator (the lower part of the fraction), and then you add that number to the numerator (higher number of the fraction). If you need to turn 2 3/4 into a fraction, you do this: 2*4=8, 8+3=11, so 2 3/4=11/4 as an improper fraction.
31/83 7/8:= [(8 * 3)+7]/8= [24 + 7]/8= 31/8 in improper fraction
The result obtained from 4 and 7 8 fraction minus 3 and 3 4 is 9/8.
7/8
31/8
31/8
9/8 = 1 and 1/8 = 9/8
If you mean 3 and 7/8 then as a decimal it is 3.875 and as a fraction it is 31/8
(24/7) / 8 = 24/(7*8) = 3/7
1/2 + 3/8 = 7/8.
