Answer
$\frac{3}{4}\lt\frac{7}{8}$
Work Step by Step
To compare the values of $\frac{3}{4}$ and $\frac{7}{8}$, you first need to find the least common denominator. To do this, you first see if the greater of the two denominators can be divided by the lesser. Since 8 can be divided by 4 to get 2, you multiply $\frac{3}{4}$ by $\frac{2}{2}$ (which is 1 expressed as a fraction with a denominator of 2) to get $\frac{6}{8}$. You can compare this new fraction to $\frac{7}{8}$ since they now share a common denominator.
Since $6\lt7$, $\frac{6}{8}\lt\frac{7}{8}$.
