Begin by rewriting the given mixed numbers as improper fractions. To add or subtract fractions, they need to have the same denominator.
4 29
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 59 | 2* 9+5/9 | 23/9 |
| 1 23 | 1* 3+2/3 | 5/3 |
When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators.
Now that we have a common denominator, we can proceed to simplifying the expression.
