Question

Mira finished 2/5 of a puzzle in 1/ 5 of an hour. At this rate, how many puzzles could she finish in 1 hour

Answer 1

If the puzzle was solved in 1/5 hour, we can multiply the time it took to solve one puzzle by 5.

2/5(5/1)
=10/5
=2

So she'll be able to solve 2 puzzles in one hour.

Answer 2

She could finish 2 puzzles

5/5=1 hr
2/5 each hr
so multiply....

2/5 x 5/5
you simplify, crossing out the 5 in the denominator and the 5 in the numerator
then you get..
2/1, which equals 2 I hope the answer is correct!
