yen=16/21=76

Answer 2

Answer:

Yen is the fastest.

Step-by-step explanation:

Ethan can blow 15 balloons in 20 minutes.

So, the balloons he can blow in 1 minute = 15/20 = 0.75

Joe can blow 18 balloons in 25 minutes.

So, the balloons he can blow in 1 minute = 18/25 = 0.72

Yen can blow 16 balloons in 21 minutes.

So the balloons he can blow in 1 minute = 16/21 = 0.76

Thus, from 0.75, 0.72, 0.76 ; 0.76 is the highest number. So we can say Yen is the fastest among the three.
