Change to higher terms; each number to be of the same denominator.

5-3%2F4
Notice the common denominator should be 4.

5%284%2F4%29-3%2F4

20%2F4-3%2F4

highlight%284%261%2F4%29



8%263%2F5-2%268%2F9
Notice the denominator should be 5%2A9=45.

8%2B%283%2F5%29%289%2F9%29-%282%2B%288%2F9%29%285%2F5%29%29

8%2B27%2F45-%282%2B40%2F45%29

8-2%2B27%2F45-40%2F45
6-13%2F45
You can borrow from the 6 whole part.
