Question

The ratio of green to yellow M&M's is 2:5.

If there are 18 green M&M's in the bag, how many are yellow?

Answer 1

45 yellow ones, i think

for every 2 green, there are 5 yellow

there are 18 green, so 9 pairs

9 times 5 = 45 (i multiplied by 5 because there are 5 yellow for each pair of green)
