Exercise 5 Page 294

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

5/8

Practice makes perfect

When adding or subtracting fractions, they should have the same denominator. In this exercise, we have two fractions with different denominators. 3/8 - (- 1/4)Since 8 is a multiple of 4, we can multiply both the numerator and denominator of - 14 by 2 to create a common denominator.

3/8-(- 1/4)

a/b=a * 2/b * 2

3/8-(- 1* 2/4* 2)

Multiply

3/8-(- 2/8)

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

3/8-(- 2/8)

a-(- b)=a+b

3/8+2/8

Add fractions

3+2/8
