Question

The main ingredients for Kayla’s banana bread recipe are 2 1/3 cups of flour, 3/4 cup of sugar? And 1 1/2 cups of mashed bananas. How many more cups of dry ingredients (flour and sugar) then wer ingredients (bananas) go into Kayla’s banana bread? Explain

Answer 1

`1 (7)/(12) \ \textsf{cups}`

Explanation:

Banana bread recipe:

• Flour =
  `2 \frac13` cups
• Sugar =
  `\frac34` cups
• Banana =
  `1 \frac12` cups

Dry ingredients = flour + sugar

`=2 \frac13+\frac34=\frac73+\frac34=(37)/(12) \ \textsf{cups}`

Difference = dry ingredients - bananas

`=(37)/(12)-1 \frac12\\\\=(37)/(12)-\frac32\\\\=(37)/(12)-(18)/(12)\\\\=(19)/(12)\\\\=1(7)/(12) \ \textsf{cups}`
