Given:
a.) April was making two different cakes.
b.) One cake recipe needed 7/9 cup of flour.
c.) The other cake needed 5/9 cup of flour.
Determining how many cups will April be needing means we will be adding the number of cups needed on each cake.
Since 7/9 and 5/9 are like fractions (with the same denominator), we can directly add the two fractions.
To do this, we just add the numerator and copy the denominator.
We get,
[tex]\text{ }\frac{\text{ 7 }}{\text{ 9 }}\text{ + }\frac{\text{ 5 }}{\text{ 9 }}[/tex][tex]\text{ = }\frac{\text{ 7 + 5}}{\text{ 9}}[/tex][tex]\text{ = }\frac{\text{ 12 }}{\text{ 9 }}[/tex][tex]\text{ = }\frac{\text{ 4 }}{\text{ 3 }}\text{ or 1 }\frac{1}{3}\text{ cups}[/tex]
Therefore, April will be needing 4/3 or 1 1/3 cups of flour to make the two cakes.
