30. Daniel puts some wheat flour into an empty bowl. Then he adds #2/3# cup rye flour to make a total of #2 5/12# cups of flour. How much wheat flour is in the bowl?

Question

Autumn Arnold · Accepted Answer

#1 3/4# cups of wheat flour

To find out how much wheat flour was in the bowl before Daniel added rye flour, you have to subtract the total amount of flour by the rye flour he added. #2 5/12 - 2/3# First, find the common denominator so you can subtract the fractions. To do that, multiply both sides of 2/3 by 4 to get the denominator 12. #2/3 * 4/4 = 8/12# You cannot subtract 8/12 from 2 5/12 . Borrow a whole from 2 by adding 12/12 to 5/12 . #2 5/12 -> 1 17/12# Subtract. #1 17/12 - 8/12 = 1 9/12# Simplify. #1 9/12 -> 1 3/4#

undefined To find out how much wheat flour is in the bowl, we can subtract the amount of rye flour from the total amount of flour.

The total amount of flour in the bowl is given as 2 5/12 cups.

Daniel added 2/3 cup of rye flour.

To find the amount of wheat flour, we subtract the amount of rye flour from the total amount of flour:

Total flour - Rye flour = Wheat flour

2 5/12 - 2/3 = Wheat flour

To subtract the fractions, we need to find a common denominator, which in this case is 12:

2 5/12 - 8/12 = Wheat flour

Now, we can subtract:

2 5/12 - 2/3 = 19/12 - 8/12 = 11/12

So, there are 11/12 cups of wheat flour in the bowl.
