Answer: 7 9/20
Turn 14 1/4 into an Improper Fraction
Multiply 14*4 and get 56. Now add 1 and get 57.
14 1/4 = 57/4
Turn 6 4/5 into an Improper Fraction
Multiply 6*5 and get 30. Now add 4 and get 34.
6 4/5 = 34/5
Your new problem should be: 57/4 - 34/5
Subtract
57/4 - 34/5 = 149/20
Turn 149/20 into a Mixed Number
149 ÷ 20 = 7.45
7.45 = 7 9/20
