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
8 34
8* 4+3/4
35/4
4 56
4* 6+5/6
29/6
In this exercise, we have two fractions with different denominators.
35/4 - 29/6
Now, we have to multiply the numerator and the denominator in both fractions to create a common denominator.
