Question

compare, using subtraction and division, the amount of sugar used in two recipes, if Recipe 1 used two and two thirds (2 2/3) cups and Recipe 2 used one and a half (1 1/2) cups. Show your calculations and then write your answers as sentences.​

Answer 1

Answer:

Recipe 1 used $1\frac{7}{9}$ times as many cups and $1\frac{1}{6}$ more cups than Recipe 2.

Step-by-step explanation:

By subtraction:

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

$\frac{8}{3}$ - $\frac{3}{2}$

$\frac{8*2}{3*2}$ - $\frac{3*3}{2*3}$

$\frac{16}{6}-\frac{9}{6} = \frac{7}{6} =1\frac{1}{6}$ cups more

By division:

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

$\frac{8}{3}$ / $\frac{3}{2}$

$\frac{8}{3}$ * $\frac{2}{3}$

$\frac{8*2}{3*3}=\frac{16}{9} =1\frac{7}{9}$ times as many cups more
