Exercise 7 Page 295

When adding or subtracting fractions, they should have the same denominator. In this exercise, we are given two fractions with different denominators. - 4/9 - 2/15 To add fractions, their denominators need to be the same. Since 45 is the least common denominator of the two fractions, we can multiply both the numerator and denominator of - 49 by 5 and 215 by 3 to create a common denominator. We will start with the first fraction.

Let's continue with the second fraction.

Now, since the denominators are the same, we can subtract the fractions.
