Nina has 2 cups of flour. However, this is only 1/4 of the amount of flour that she needs for a bread recipe. How many cups of flour does the recipe call for?
Since 2 cups are only 1/4 of what she needs, you can also say that she needs 4 times that amount. Because of that, she needs 8 cups. To check, 2 divided by 8 is .25, which is equivalent to 1/4.
