4. Dividing fractions examples


1. Find 1/2 / 3/4

Solution:
=(1)/(2) -: (3)/(4)

=(1)/(2) xx (4)/(3)

=(1xx4)/(2xx3)

=(1xx2*2)/(2xx3) (Find factors)

=(1xxcancel{(2)}*2)/(cancel{(2)}xx3) (Remove common factors)

=(2)/(3)
2. Find 3/4 / 5/6

Solution:
=(3)/(4) -: (5)/(6)

=(3)/(4) xx (6)/(5)

=(3xx6)/(4xx5)

=(3xx2*3)/(2*2xx5) (Find factors)

=(3xxcancel{(2)}*3)/(cancel{(2)}*2xx5) (Remove common factors)

=(9)/(10)
3. Find 3/4 / 3/2

Solution:
=(3)/(4) -: (3)/(2)

=(3)/(4) xx (2)/(3)

=(3xx2)/(4xx3)

=(3xx2)/(2*2xx3) (Find factors)

=(cancel{(3)}xxcancel{(2)})/(cancel{(2)}*2xxcancel{(3)}) (Remove common factors)

=(1)/(2)
4. Find 3/4 / 2/3

Solution:
=(3)/(4) -: (2)/(3)

=(3)/(4) xx (3)/(2)

=(3xx3)/(4xx2)

=(9)/(8)

=1 (1)/(8) (Converting improper fraction to mixed number)
5. Find 1/2 * 3/4 / 5/6

Solution:
=(1)/(2) xx (3)/(4) -: (5)/(6)

=(1)/(2) xx (3)/(4) xx (6)/(5)

=(1xx3xx6)/(2xx4xx5)

=(1xx3xx2*3)/(2xx2*2xx5) (Find factors)

=(1xx3xxcancel{(2)}*3)/(cancel{(2)}xx2*2xx5) (Remove common factors)

=(9)/(20)
