Hi again Jackeline;
The quantity of juice is presented in pints.
The capacity of the glasses is presented in ounces.
We need our units aligned.
Juice...2 1/2 pints
Glasses...5 ounces
 
2 1/2 pints(16 ounces/1 pint)
Let's cancel units...
2 1/2 pints(16 ounces/1 pint)
2 1/2(16 ounces)
40 ounces
 
Juice...40 ounces
Glasses...5 ounces
5 ounces(x)=40 ounces
x=quantity of glasses
5 ounces(x)=40 ounces
5x=40
Let's divide both sides by 5...
[5(x)]/5=40/5
x=8
