Charles put
2
7
gallons of gasoline in 100 bikes equally. How many bikes will Charles fill with a gallon of gasoline?
Explanation
100 ÷ 2/7
100/1 ÷ 2/7
Keep the first fraction as it is. Change division sign to multiplication and flip the second fraction.
100/1 x 7/2
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
= (100 x 7)/(1 x 2)
= 700/2
That can be simplified to
= 350
