When adding or subtracting fractions, they should have the same denominator. In this exercise, we are given two fractions with different denominators.
- 5/6 + ( - 4/9)
To add fractions, their denominators need to be the same. Since 18 is the least common denominator of the two fractions, we can multiply both the numerator and denominator of - 56 by 3 and - 49 by 2 to create a common denominator. We will start with the first fraction.
