Brian irons 2/9 of his shirt in 3 3/5 minutes. If Brian irons at a constant speed how much of his shirt does he iron in a minute

Question

Please help?

Answer 1

Set up a proportion (shirt ironed/minutes = shirt ironed/minutes). I'll convert 3 3/5 to an improper fraction as well to set it up.

 

(2/9) / (18/5) = x / 1

 

Cross multiply to get

 

2/9 = (18/5)x

 

Multiply both sides by 5/18 to solve for x.

 

10/162 = 5/31
