Before we can evaluate a sum or difference involving mixed numbers, the mixed numbers must first be rewritten as fractions.
a bc
a* c+b/c
Simplify
- 3 14
- ( 3* 4+1/4)
- 13/4
- 1 34
- ( 1* 4+3/4)
- 7/4
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with the same denominator.
- 13/4 + ( - 7/4)
Because we have a common denominator, we can proceed to simplifying the expression.
