The frequency table below shows the amount of oatmeal, in cups, 10 runners ate before a race. How many cups of oatmeal did the runners eat in total?

A table with 2 columns, cups and runners. Row 1, 1 cup and 2 runners. Row 2, 1 and 1 quarter cups and 1 runner. Row 3, 1 and 1 half cups and 3 runners. Row 4, 1 and 3 quarter cups and 2 runners. Row 5, 2 cups and 2 runners.

To find the total amount of oatmeal eaten by the runners, we need to add up the amounts of oatmeal from each row.

Row 1: 1 cup x 2 runners = 2 cups
Row 2: 1 and 1/4 cups x 1 runner = 1 and 1/4 cups
Row 3: 1 and 1/2 cups x 3 runners = 4 and 1/2 cups
Row 4: 1 and 3/4 cups x 2 runners = 3 and 1/2 cups
Row 5: 2 cups x 2 runners = 4 cups

Total: 2 cups + 1 and 1/4 cups + 4 and 1/2 cups + 3 and 1/2 cups + 4 cups = 15 and 1/4 cups.

The runners ate a total of 15 and 1/4 cups of oatmeal.
