A shop sells jackets in three sizes. The ratio of the number of small jackets to the number of medium jackets is 5:9. The number of large jackets is 3 times the number of small jackets. What is the ratio of the number of medium jackets to the number of large jackets?

1 answer

Let the number of small jackets be 5x and the number of medium jackets be 9x. Then the number of large jackets is 3*(5x) = 15x.

The ratio of the number of medium jackets to the number of large jackets is 9x:15x or 9:15. Dividing both sides of the ratio by 3, we get 3:5.

Therefore, the ratio of the number of medium jackets to the number of large jackets is 3:5.
