Question

I purchased the red and green mm's for holidays. There were 1800 mm's in the bag. Surprisingly, the ratio of red mm's to green mm's was 4 to 5. How many less red mm'swere there in the bag

Answer 1

200

Explanation:

The total number of "ratio units" is 4+5 = 9, so each one stands for 1800/9 = 200 M&Ms.

The difference in red and green ratio units is 1 unit, so the difference in the count of M&Ms will be 200 pieces.
