Exercise 6 Page 295

When adding or subtracting fractions, they should have the same denominator. In this exercise, we are given two fractions with different denominators. - 7/12 + 7/10 To add fractions, their denominators need to be the same. Since 60 is the least common denominator of the two fractions, we can multiply both the numerator and denominator of - 712 by 5 and 710 by 6 to create a common denominator. We will start with the first fraction.

- 7/12

ExpandFrac

a/b=a * 5/b * 5

- 7* 5/12* 5

- 35/60

Let's continue with the second fraction.

7/10

ExpandFrac

a/b=a * 6/b * 6

7*6/10*6

Multiply

Multiply

42/60

Now, since the denominators are the same, we can add the fractions.

- 35/60+42/60
