Question

It took Mike 1/3 hour to mow 1/4 of a yard. How long will it take him to finish the entire yard?

Answer 1

Answer:

4/3 of an hour, or 1.33 hours

Step-by-step explanation:

It took Mike 1/3 of an hour to mow 1/4 of the yard. This means when it has been 1 full hour, he would have mowed 3/4 of the yard, because $\frac{1}{3} *3=1$ hour. Because of this, we can multiply 1/3 by 4, because he has to mow 4 parts of his lawn, and he can do 1 part in 1/3 of an hour.

$\frac{1}{3} *\frac{4}{4} =4/3$ hours
