Question

There are approximately 210 M&M’s in a 7-ounce bag of M&M’s. a. Write and solve a proportion that you can use to find the number of M&M’s in a 3-ounce bag. b. What is the number of M&M’s per ounce? c. Approximately how many ounces does each M&M weigh? Round to the nearest hundredth.

Answer 1

210/7 = 30 so there are 30 M&Ms per ounce. 30 * 3 = 90 so there are 90 M&Ms in 3 ounces. Each M&M weighs 1/30 of an ounce and in decimal form that is 0.0333 repeating so rounded to the nearest hundredth it would be 0.03 ounces per M&M.
