Question

A cooking for the nursing home is preparing 100 yeast rolls for dinner the dry ingredients needed include 14 1/8 cups of flour 6 3/8 cups of sugar and 3/8 cups of salt how many cups of dry ingredients are in this recipe

Answer 1

`20(7)/(8)cups\text{ or 19}(15)/(8)\text{of dry ingredients}`

Explanations:

Given the following ingredients

Cups of flour = 14 1/8 = 113/8 cups

Cups of sugar = 6 3/8 cups = 51/8 cups

Cups of salts = 3/8 cups

Calculate the total cups of dry ingredients

`Total\text{ cups}=(113)/(8)+(51)/(8)+(3)/(8)`

Find the LCM

`\begin{gathered} Total\text{ cups}=(113+51+3)/(8) \\ Total\text{ cups}=(167)/(8) \\ Total\text{ cups}=20(7)/(8)cups \\ Total\text{ cups}=19+1(7)/(8) \\ Total\text{ cups}=19+(15)/(8) \\ Total\text{ cups}=19(15)/(8)cups \end{gathered}`

Therefore there are 19 15/8 cups of dry ingredients in this recipe
