Jessica is a custodian at oracle arena. she waxes 20m^2 of the floor in 3/5 of an hour.
at this rate, how many square meters can she wax per hour?

To figure the answer you're going to want to figure how much time 3/5 of an hour is so make an equation, 60/5 which equals 12. so in 36 minutes she waxes 20m². so we now know that it takes 36 minutes to do her 20m². 24 minutes remain or 2/5. we ow need to figure out how much is waxed in the 36 minutes or 3/5. 20 divided by the 3, from the 3/5, we get 6.666666667, multiply that by 2 you get13.333333334. addthat to 20 you get 33.333333334m²
so they should accept33.33m²

She should use 12/3 to measure

That is right sorry i was gonna answer but i already saw his
