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
10 45
10* 5+4/5
54/5
2 15
2* 5+1/5
11/5
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with the same denominator.
54/5 - 11/5
Because we have a common denominator, we can proceed to simplifying the expression.
