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?
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
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.
