Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant ra
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.
