A recipe for brownies calls for 4 eggs and 1 1/2 cups of flour. If the recipe makes 15 brownies, how many cups of flour will be needed to make 60 brownies?

Step-by-step explanation:

If the recipe makes 15 brownies and you need 60 start by dividing 60 by 15.

60÷15=4

So you would need to make 4 batches of brownies. Which also means that to make it every ingredient is multiplied by 4. Since we are looking for flour 1.5 times 4 is what we need.

1.5 x 4 = 6

You need 6 cups of flour.
