Answer: 21
=========================================================
Work Shown:
14/20 = 70/100 after multiply top and bottom by 5
70/100 = 70%
Drake makes 70% of his free throws
If he attempts 30 of them, then he should make about 0.70*30 = 21
-----------
Alternative Method:
(amount made)/(amount attempted) = (amount made)/(amount attempted)
14/20 = x/30
14*30 = 20*x ... cross multiply
420 = 20x
20x = 420
x = 420/20
x = 21
This is another way to see that we expect Drake to make about 21 free throws.
