Step-by-Step Solution

We must first identify the lowest common denominator between 4 and 8.

In order to determine the lowest common denominator, we need to find a number that is divisible by both 4 and 8.

In this case, the common denominator is 8.

We'll then proceed to multiply each fraction by the appropriate number to reach the denominator 8.

We'll multiply the first fraction by 2

We'll multiply the second fraction by 1

$\frac{3\times2}{4\times2}+\frac{1\times1}{8\times1}=\frac{6}{8}+\frac{1}{8}$

Finally we'll combine and obtain the following:

$\frac{6+1}{8}=\frac{7}{8}$
