Question

Ms. Palma is baking a cake. She used 2 3/4 cups of flour to make the cake. She used 1 1/2 of flour to bake the cookies. How many cups of flour did she use altogether?

Answer 1

Answer: There are $3\dfrac{3}{2}\ cups$ of flour she would use altogether.

Step-by-step explanation:

Since we have given that

Amount used by her to make the cake = $2\dfrac{3}{4}=\dfrac{11}{4}$

Amount used to bake the cookies = $1\dfrac{1}{2}=\dfrac{3}{2}$

So, the number of cups of flour is given by

$\dfrac{11}{4}\div \dfrac{3}{2}\\\\=\dfrac{11}{4}\times \dfrac{2}{3}\\\\=\dfrac{11}{2\times 3}\\\\=\dfrac{11}{3}\\\\=3\dfrac{2}{3}$

Hence, there are $3\dfrac{3}{2}\ cups$ of flour she would use altogether.
