Question

Mrs. Jennings had 5/7 gallons of paint. She gave 1/7 gallon each to some students. How many students received paint if Mrs. Jennings gave away all of the paint

Answer 1

To get the answer we have to divide 5/7 by 1/7.
To divide 2 fraciton we can multiply first by inverse of second.
$\frac{5}{7} : \frac{1}{7}= \frac{5}{7} * \frac{7}{1} = \frac{5*7}{7*1} = \frac{35}{7}=5$ - its the answer
