Exercise 2 Page 661

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

3 14

Practice makes perfect

To add fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 5/2 + 3/4 Since 4 is a multiple of 2, we can multiply both the numerator and denominator of 52 by 2 to create a common denominator.

5/2 + 3/4
5 * 2/2 * 2 + 3/4
10/4+3/4

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

10/4+3/4
10+3/4
13/4

Therefore, 134 is the result of the sum of the fractions. However, we can also write our answer as a mixed number.

13/4
â–¼
Write as mixed number
12+1/4
12/4+1/4
3+1/4

Finally, the expression 3+ 14 can be read as 3 and 14. Therefore, it can be written as 3 14. 5/2+3/4=13/4 ⇔ 5/2+3/4=3 14
