If a recipe calls for 2/3 cups of sugar but I only want to make 1/4 of the recipe, how much sugar do I need?

(0.064)(2*pi*h)+(0.064)*4*pi*r=z*2*pi*r*h

(0.064)2*pi*r=z*pi*r^2

pi*r^2*h=1567.8

Find r,h,z

1/4 * 2/3 = 2/12 = 1/6

The answer is 1/6 because all you have to do is 2/3 x 1/4 and you will get 2/12 reduce that to 1/6 so its just saying 2/3 of 1/4 is 1/6 the symbol x means of so this of this is this

To find out how much sugar you need, you'll need to perform a proportionate calculation. Here's how you can do it:

Step 1: Determine the ratio between the original recipe and the desired amount. In this case, you want to make 1/4 of the recipe, which means you have a ratio of 1/4.

Step 2: Take the original amount of sugar (2/3 cups) and multiply it by the ratio.

2/3 cups x 1/4 = (2/3) x (1/4) = 2/12 = 1/6 cups of sugar

So, if you want to make 1/4 of the recipe, you'll need approximately 1/6 cups of sugar.
