Question

Brian irons 2/9 of his shirt in 3 3/5 minutes. At this rate, how much of his shirt does he iron each minute?

Answer 1

The speed for which Brian iron the shirts is given by:

$R = \frac{\frac{2}{9}}{3\frac{3}{5}}$

Rewriting we have:

$R = \frac{\frac{2}{9}}{\frac{18}{5}}$

$R = \frac{10}{162}$

Then, for each minute, we have the amount of ironed shirt is:

$(\frac{10}{162})(1) = \frac{10}{162}$

Answer:

At this rate, Brian plans 10/162 of his shirt.

Answer 2

You have to divide both sides by 3 3/5
Or multiply by 5/18, the inverse of 3 3/5.

It should get you 5/81 of his shirt per minute
