Answer 1

Answer:

$9 \frac{3}{4}$ sups of milk

Step-by-step explanation:

It is given that;

4 : 3 (this represents the proportion of cups of oats to cups of milk)

Now one has to find how many cups of milk will correspond with 9 cups of oats.

First, convert the given ratio to a unit ratio,

4 : 3

/4  /4

1 : $\frac{3}{4}$

Now multiply the entire ratio by 9 to find out how many cups of milk corresponds to 9 cups of oats;

9 : $\frac{39}{4}$

Simplify;

9 : $9 \frac{3}{4}$
