a recipe for making 54 biscuits requires 9 cups of biscuit mix.
Using this recipe, how many cups of biscuits mix will be needed to make 18 biscuits?
To solve this problem, we can use ratios. We know that 54 biscuits require 9 cups of biscuit mix. We can set up a ratio like this:
54 biscuits/9 cups = 18 biscuits/x cups
We want to solve for x, which represents the number of cups of biscuit mix needed to make 18 biscuits. We can cross-multiply and simplify the ratio:
54x = 9 x 18
54x = 162
x = 3
Therefore, to make 18 biscuits, we will need 3 cups of biscuit mix.
