Question

Add: 3 cups 6 oz + 2 cups 9 oz

Answer 1

We have the following:

First we must seek equality between ounces and cups

1 cup = 8 oz

therefore

`\begin{gathered} 3\cdot8+6=24+6=30 \\ 2\cdot8+9=25 \\ 30+25=55 \end{gathered}`

Which means that in total there are 55 ounces

now we look for the equivalence of 55 ounces in cups and ounces

`\begin{gathered} 5\cdot8+7=40+7=47 \\ 6\cdot8+7=48+7=55 \end{gathered}`

The answer so is 6 cups and 7 oz
