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.

Two athletes ate

\frac{1}{4}

cup of oatmeal. Add

\frac{1}{4}

cup, two times.

\frac{1}{4}

cup +

\frac{1}{4}

cup =

\frac{2}{4}

cup

So, the athletes who ate

\frac{1}{4}

cup of oatmeal, ate a total of

\frac{2}{4}
