There are 55 M&Ms in the holiday pack and they are all green or red. There are 20 green M&Ms and the rest are red. What is the ratio of red M&Ms to total M&Ms?

7 : 11

Step-by-step explanation:

x represents red, y represents green.

Based on the given information;

x + y = 55

There are 20 M&Ms that are green, hence;

y = 20

Substituting this back into the first equation;

x + y = 55

x + 20 = 55

x = 35

The ratio of red : total would then be;

35 : 55

Divide both sides by 5

7 : 11
