what is 1/2 as a decimal?
1/2 as a decimal is 0.5.
To find out how much butter Jennie needs, we can use a simple proportion.
The original recipe calls for 3 tablespoons of kernels and 1/2 cup of butter. We want to know how much butter she needs when using 10 tablespoons of kernels.
Step 1: Set up the proportion:
3 tablespoons of kernels / 1/2 cup of butter = 10 tablespoons of kernels / x cups of butter
Step 2: Cross-multiply:
3 * x = 10 * 1/2
Step 3: Simplify:
3x = 5
Step 4: Solve for x (cups of butter):
x = 5/3 ≈ 1.67 cups
Therefore, Jennie needs approximately 1.67 cups of butter when using 10 tablespoons of kernels.
