how many cups of butter is needed for 36 brownies?...if 2/3 cups is need for 16 brownies

(36/16) x (2/3) = ___ cups

(2/3)/16 = x/36

Cross multiply and solve for x.

16x = (2/3)*36
16x = 72/3
16x = 24
x = 24/16
x = 1 8/16 = 1 1/2

To find how many cups of butter are needed for 36 brownies, we can use the information given.

We know that 2/3 cup of butter is needed for 16 brownies.

So, we can set up a proportion to find the amount for 36 brownies.

Let's call the unknown amount of butter for 36 brownies "x".

The proportion would be:

2/3 cups / 16 brownies = x cups / 36 brownies

To solve this proportion, we can use cross-multiplication:

(2/3) * 36 = 16 * x

Multiplying both sides:

(2/3) * 36 = 16x

72/3 = 16x

24 = 16x

Now, divide both sides by 16 to solve for x:

24/16 = x

1.5 = x

Therefore, you would need 1.5 cups of butter for 36 brownies.
