Exercise 21 Page 1

When adding or subtracting fractions, they need to have the same denominator.

11/14

In this exercise, we have two fractions with different denominators. 4/7 + 3/14Since 14 is a multiple of 7, we can multiply both the numerator and denominator of 47 by 2 to create a common denominator.
4/7+3/14
4 * 2/7 * 2+3/14
8/14+3/14
Now that we have a common denominator, we can proceed to simplifying the expression.
8/14+3/14
8+3/14
11/14
