Thomas is making hummus. One of the ingredients in a hummus recipe is chickpeas. For one serving of hummus, the recipe calls for 1 cup of chickpeas. In a can of chickpeas, there are 16 ounces of chickpeas. In one cup of chickpeas, there are 6 ounces. To make 20 servings, how many cans of chickpeas should Thomas buy?
For 20 servings, Thomas needs 20*1 = <T>multiply(20, 1)=20 cups of chickpeas.
To have 20 cups, Thomas needs 20*6 = <T>multiply(20, 6)=120 ounces.
120 ounces/16 ounces = <T>divide(120, 16)=7.5 cans of chickpeas.
Since Thomas cannot buy half a can, he needs to buy 8 cans.
