Question

7) What is the sum?
1/9 + 5/9 = ?

Answer 1

6/9 is the sum. The fractions already have common denominators, and thus their numerators can be added together.

Answer 2

`(1)/(9) +(5)/(9)`

Since The denominators are the same, only add the numerators.

`(1)/(9) +(5)/(9)`

`1+5=6`

`=(6)/(9)`

Simplify:

`(6/3)/(9/3)`

`=\fbox{$(2)/(3) $}`
