Exercise 34 Page 329

Practice makes perfect

When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 11/12 - 2/3Since 12 is a multiple of 3, we can multiply both the numerator and denominator of 23 by 4 to create a common denominator.

11/12 - 2/3

ExpandFrac

a/b=a * 4/b * 4

11/12 - 2* 4/3* 4

Multiply

11/12 - 8/12

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

11/12 - 8/12

When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 3/8 + 7/12Since 24 is a multiple of 8 and 12, we can multiply both the numerator and denominator of 38 by 3 and both the numerator and denominator of 712 by 2 to create a common denominator.

3/8 + 7/12

ExpandFrac

a/b=a * 3/b * 3

3* 3/8* 3 + 7/12

ExpandFrac

a/b=a * 2/b * 2

3* 3/8* 3 + 7* 2/12* 2

Multiply

9/24 + 14/24

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

9/24 + 14/24

When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 9/10 + 5/8Since 40 is a multiple of 10 and 8, we can multiply both the numerator and denominator of 910 by 4 and both the numerator and denominator of 58 by 5 to create a common denominator.

9/10 + 5/8

ExpandFrac

a/b=a * 4/b * 4

9* 4/10* 4 + 5/8

ExpandFrac

a/b=a * 5/b * 5

9* 4/10* 4 + 5* 5/8* 5

Multiply

36/40 + 25/40

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

36/40 + 25/40
