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
14 16
14* 6+1/6
85/6
7 13
7* 3+1/3
22/3
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with the same denominator.
85/6 - 22/3
Since 6 is a multiple of 3, we can multiply both the numerator and denominator of 223 by 2 to create a common denominator.
