A recipe uses 3 cups of flour to make 48 cookies. How much flour is needed to make 72 cookies?
My answer is 3/48 = x/72, x = 4.5\
Can someone check my answer please?
One cup of flour can make .0625 cookies. You have to multiply by 72 to figure out how many cups it takes to make 72 cookies. Therefore, it takes 4.5 cups. So you are correct.
Your calculation is correct! You used a proportion to solve the problem, which is a valid approach. Let me explain the steps in more detail:
To find out how much flour is needed to make 72 cookies, you can set up a proportion using the given information:
3 cups of flour / 48 cookies = x cups of flour / 72 cookies
Then, we cross-multiply and solve for x:
48 * x = 3 * 72
48x = 216
x = 216 / 48
x = 4.5
So, you are correct. To make 72 cookies, you would need 4.5 cups of flour. Well done!
