gallons of paint. All of the bookcases are the same size and each requires 3/16 gallon of paint. How many bookcases will she be able to paint
The custodian will be able to repaint 7 bookcases with the amount of paint.
The custodian has 5 1/4 gallons of paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give us the number.
But first we need to change 5 1/4 to improper fraction,
thus; 5 1/4 =
5 1/4 ÷3/4 = ÷
(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;
4 will cancel out 4 hence;
Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.
