Question

Mary is baking a carrot cake. The recipe requires 2 cups of flour for every 112

cups of sugar. Mary uses 3 cups of flour. What is the number of cups of sugar Mary needs to add?

Answer 1

Answer: We can set up a proportion to solve for the number of cups of sugar Mary needs to add:

2 cups flour / 112 cups sugar = 3 cups flour / x cups sugar

Cross-multiplying, we get:

2 cups flour * x cups sugar = 112 cups sugar * 3 cups flour

Simplifying, we get:

2x = 336

Dividing both sides by 2, we get:

x = 168

Therefore, Mary needs to add 168 cups of sugar.
