Answer 2

The largest fraction is $\frac{7}{8}$

Step-by-step explanation:

In order to determine the largest Fraction we will follow the below steps:-

1) We will have to make each fraction to an equivalent fraction.

2)We can do so by making the denominator same.

3)Compare the fractions 2 at a time.

4)The one with the largest numerator is the largest.

Make each fraction to an equivalent fraction by making the denominator same:

$\frac{7}{8} =\frac{70}{80} \\\\\frac{13}{16} =\frac{65}{80} \\\\\frac{31}{40} =\frac{62}{80} \\\\\frac{63}{80}$

Comparing the fractions 2 at a time

$\frac{70}{80}>\frac{65}{80}\\\\\frac{65}{80}>\frac{62}{80} \\\\\frac{62}{80}<\frac{63}{80} \\\\\\\frac{63}{80}<\frac{70}{80} \\\\Thus:\frac{70}{80} >\frac{65}{80}>\frac{63}{80} >\frac{62}{80}$

$\frac{70}{80} =\frac{7}{8}$ is the largest fraction.
