13/18

Explanation:

To simplify these fractions, you first need a common denominator. We can use the LCM of 9 and 2, which is 18.

2/9=(2 " x " 2)/(9 " x " 2)=4/18

1/2=(1 " x " 9)/(2 " x " 9)=9/18

Finally add your fractions together:

4/18+9/18=color(red)(13/18)

Because 13/18 can not be simplified any further (as 13 is prime), this is your final answer.

13/18

Explanation:

Firstly, you have to find the least common denominator between the two fractions. The lcd is 18 since 9 can be multiplied by 2 to get 18, and 2 can be multiplied by 9 to get 18. You must then multiply the numerator by the number you multiplied the denominator of the same fraction. Doing this you get:
4/18+9/18=13/18
This cannot be reduced any further, therefore 13/18 is your answer.
