Bob solved 68 puzzle in
4
7
of an hour. He used the same amount of time in solving each puzzle. How many puzzles will Bob solve in an hour?
Explanation
68 ÷ 4/7
68/1 ÷ 4/7
Keep the first fraction as it is. Change division sign to multiplication and flip the second fraction.
68/1 x 7/4
Now, it can be done as multiplication of fractions.
Multiply both numerators together to get new numerator and multiply both denominators together to get new denominator
= (68 x 7)/(1 x 4)
= 476/4
That can be simplified to
= 119
