Exercise 5 Page 295

To add or subtract fractions, they need to have the same denominator.

4/9

Practice makes perfect

When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 7/9 - 1/3Since 9 is a multiple of 3, we can multiply both the numerator and denominator of 13 by 3 to create a common denominator.

7/9-1/3

a/b=a * 3/b * 3

7/9-1* 3/3* 3

Multiply

7/9-3/9

Now that we have a common denominator, we can proceed to simplifying the expression.
