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
7 56
7* 6+5/6
47/6
3 16
3* 6+1/6
19/6
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with the same denominator.
47/6 - 19/6
Because we have a common denominator, we can proceed to simplifying the expression.
