Answer:
3) D 2.3 yd
4) G 5/17 = y/100
Explanation:
11.5 = 100%
x = 20%
100x = 11.5 * 20 (do this multiplication, it's easy just times 10 then double it)
100x = 230
x = 230 / 100
x = 2.3
17 liters is the total punch which is 100%
5 liters is the percentage we try to find.
So 5 is a fraction of 17 at the the same rate y is a fraction of 100, yes?
