Really bad the answer i am stuck on it plz me

The ratio in Ryan's science class is 12:10 (girls:boys) which can be simplified to 6:5. In Ryan's 
orchestra group there is a ration of 22:20 which can be simplified to 11:10

11:10 and 6:5 are not the same, therefore the ratio is not equivalent.

Hope this helps :)

remains the same or changes it
