Question

Annalisa uses 2/3 cup of all purpose flour and 1/2 cup of whole wheat flour to make pancakes. How many cups of flour does she use altogether

Answer 1

first so in total you have 5 cups and out of the 5 cups there are 3 cups of flour she used 

Answer 2

For this case we have the following amounts:

• $\frac {2} {3}$ cup of all purpose flour
• $\frac {1} {2}$ cup of whole wheat flour

What we must do is add both amounts.

We have then:

$\frac {2} {3} + \frac {1} {2}$

Rewriting both fractions with the same denominator we have:

$\frac {4} {6} + \frac {3} {6}$

Adding we have:

$\frac {4} {6} + \frac {3} {6} = \frac {4 + 3} {6} = \frac {7} {6}$

Answer:

Annalisa uses$\frac {7} {6}$ cups of flour
