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
2 19
2* 9+1/9
19/9
7 49
7* 9+4/9
67/9
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with the same denominator.
19/9 + 67/9
Because we have a common denominator, we can proceed to simplifying the expression.
