Answer:

Explanation:

step 1: you know that 1/2 c of oil makes 20 cookies.

step 2: if you only have 1/4 c (half of 1/2 cup), then you can make 10 cookies.

Step 3: 1/8 c would make 5 cookies.

Answer:

We need 1/8 cup

Explanation:

We can use ratios to solve

1/2 cup x cups

------------ = -----------------

20 cookies 5 cookies

Using cross products

5 * 1/2 = 20x

Divide each side by 20

5/2 * 1/20 = 20x/20

5/40 =x

1/8 =x

We need 1/8 cup
