ELEN [110]

Answer:

B) 7/9

Step-by-step explanation:

<h3>Fraction addition:</h3>

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.

$\sf \dfrac{1}{3}=\dfrac{1*3}{3*3}\\\\$

$\sf =\dfrac{3}{9}$

Now add.

$\sf \dfrac{4}{9}+\dfrac{1}{3}=\dfrac{4}{9}+\dfrac{3}{9}\\\\$

$\sf =\dfrac{7}{9}$
