Explanation:
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.
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.
You cannot subtract 8/12 from 2 5/12 . Borrow a whole from 2 by adding 12/12 to 5/12 .
Subtract.
