Question

A recipe calls for 3 cups of flour to make 2 batches of dinner rolls. One batch makes 15 rolls. Laura is making dinner for 12 people and only needs one roll per person. What proportion will help Laura find how much flour is needed to make 12 dinner rolls?​

Answer 1

Answer: 1.2 cups of flour

Explanation:

3 cups: 2 batches

2 batches=30 rolls

required is 12 roles

3:30 then x:12

36=30x

x=6/5=1.2

Answer 2

• 1/10 cup of flour per roll

Explanation:

• 3 cups of flour ⇒ 2 batches
• 3 cups of flour ⇒ 2*15 = 30 rolls
• 1 cup of flour ⇒ 10 rolls
• 1/10 cup of flour ⇒ 1 roll

For 12 people Laura needs 12 rolls:

• 12*1/10 = 1.2 cups of flour
