Question

someone PLEASE help me. It says recipe A makes 5 dinner rolls using 1 cup of flour. Recipe B makes 24 rolls using 7 1/2 c of flour. Recipe C makes 45 rolls using 10 c of flour. which recipe requires the most flour per roll?

Answer 1

Recipe A: 5 dinner rolls with 1 cup of flour
1 cup / 5 rolls equals 1/5 cup per roll

Recipe B: 24 rolls using 7.5 cups of flour
7.5 / 24 = 5/16 cup per roll

Recipe C: 45 rolls, 10 cups of flour
10/45 = 2/9 cups per roll

1/5 = 0.2
5/16 = 0.3125
2/9 = 0.2222222...

So...which recipe requires the most flour per roll?

Answer 2

Answer 3

Answer 4

7.5 / 24 = 5/16

Answer 5

See this part:
"Recipe B: 24 rolls using 7.5 cups of flour
7.5 / 24 = 5/16 cup per roll "

Answer 6

yeah but 7.5 divided by 24 is 0.3125 and 7.5 times 24 is 180 so?

Answer 7

7.5/24 = 5/16 = 0.3125

Answer 8

Answer 9
