A **line plot** is a data display, along a number line, which shows frequency.

The frequency is indicated by a marker, like an X or a dot.

There are 2 **x**'s above $\frac{1}{4}$. This means 2 athletes ate $\frac{1}{4}$ cup of oatmeal.

There are 5 **x**'s above $\frac{1}{2}$. This means 5 athletes ate $\frac{1}{2}$ cup of oatmeal.

There are 4 **x**'s above $\frac{3}{4}$. This means 4 athletes ate $\frac{3}{4}$ cup of oatmeal.

There are 3 **x**'s above $1$. This means 3 athletes ate $1$ cup of oatmeal.

First, find the totals for each value. Then, find the sum of those totals.

for $\frac{1}{4}$: $2$ × $\frac{1}{4}$ = $\frac{2}{4}$

for $\frac{3}{4}$: $4$ × $\frac{3}{4}$ = $\frac{12}{4}$

Now, find the sum of $\frac{2}{4}$ and $\frac{12}{4}$.

$\frac{2}{4}$ + $\frac{12}{4}$ = $\frac{14}{4}$ = $3\frac{2}{4}$

So, the athletes who ate $\frac{1}{4}$ cup and $\frac{3}{4}$ cup ate a total of $3\frac{2}{4}$ cups of oatmeal.
