Question

Work out
5 3/4 - 2 1/4

7 2/3 + 2. 1/5

Answer 1

Answer:

First of all change mixed fractions to improper fractions

i.e. 5 3/4 = 23/4

    2 1/4 = 9/4

    7 2/3 = 23/3

    2 1/5 = 11/5

Now solution,

5 3/4 - 2 1/4 =>  23/4 - 9/4 => (23 - 9)/4 => 14/4 => 7/2

7 2/3 + 2. 1/5 => 23/3 - 11/5 => (115 - 33)/15 => 82/15
