Answer:
48
Step-by-step explanation:
Multiplying the ratio of raisins to M&Ms by 20, we find there are a total of 80 M&Ms in the bag.
raisins : M&Ms = 1 : 4 = 20 : 80
The ratio of peanut to plain M&Ms is 2 : 3, a total of 2+3 = 5 ratio units. These stand for a total of 80 M&Ms, so each ratio unit of M&Ms stands for 80/5 = 16 M&Ms. That is ...
peanut : plain = 2 : 3 = 32 : 48
There are 48 plain M&Ms in the bag.
