Answer 2

B) 7/9

Explanation:

Fraction addition:

• If the denominators are not same, find the LCM of the denominators.

LCM of 3 and 9 is 9.

• Now, find equivalent fractions with denominator as 9.

`\sf (1)/(3)=(1*3)/(3*3)\\\\`

`\sf =(3)/(9)`

• Now add.

`\sf (4)/(9)+(1)/(3)=(4)/(9)+(3)/(9)\\\\`

`\sf =(7)/(9)`
