Ghella [55]

to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

$\frac{20}{3/5} = \frac{x }{1 }$

you can use cross multiplication to solve for x:

$\frac{3}{5} x = 20$

$3x = 100\\x = 100/3$

so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
