3 ounces make 1 quart.
1 ounce makes 1/3 quart.
20 ounces make 20/3 quarts = 6 2/3 quarts.

Let x= number of quarts made from 20 ounces of powder milk
Then,
3/20= 1/x
x= 6 2/3 or 6.67

First, set up a proportion where you can see the ratios between ounces and quarts.
(3 oz./ 1 qt.) = (20 oz./ X qt.)
Actually, when you write the fractions in a vertical way, it's easier to see.
Next, cross multiply the 20 and 1, then divide that (20) by 3.
Your answer should be 6 and 2/3 quarts.
I hope that explanation made enough sense that you can replicate it! Good luck!

Reading a textbook never hurt anyone.
3/1 = 20/x
Cross multiply.
3x = 20
x = 20/3 quarts
