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 <span>2 I hope the answer is correct!</span>

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.
