Question

solve this oneeeeeee.​

Answer 1

Step-by-step explanation:

21 mins - - > 16 balloons

x - - > 1 balloon

Cross multiply

x = 21 x 1 / 16

x = 21/16

x = 1.3125 mins to blow one balloon

21 mins - - >16 balloons

1 mins - - > x

Cross multiply

x = 16 x 1 / 21

x = 16/21

x = 0.762 balloons in one minute
