Question

There were a total of 40 Jolly Ranchers hidden in Mr. Godsey's drawer. The ratio of red to blue is 2:5. If he had 12 red Jolly Ranchers, how many blue Ranchers does he have?

Answer 1

no answer

Explanation:

what you would do first is reduce the ratio for easier calculations. for every 2 red ones, you have 5 blue ones. we know that there are 12 red ones in total, `12/2=6`.

`6` x `5=30`.

the problem arises when you add 12 and 30 as you get 42. since there are only 40 candies, this won't work.

another hint is seeing the `2:5` and knowing the two numbers add to 7. 7 is not a factor of 40.
