Card 0 of 20
In order to divide fractions, we first take the reciprocal of the second fraction. To find the reciprocal, we switch the numerator and the denominator. So, the reciprocal of 
is 
.
Then we multiply the first fraction and the reciprocal.
We then multiply the numerators together: 
.
Then we multiply the denominators together: 
.
We divide the numerator (25) by the denominator (24) to get 
.
