Steps to Solve
- Find a common denominator
To subtract the fractions, we need a common denominator. The denominators are 9 and 3. The least common denominator (LCD) is 9.
- Rewrite the fractions with the common denominator
We rewrite the second fraction, $\frac{1}{3}$, so it has the same denominator as the first fraction. We can do this by multiplying the numerator and denominator by 3:
$$ \frac{1}{3} = \frac{1 \times 3}{3 \times 3} = \frac{3}{9} $$
- Subtract the fractions
Now that we have the same denominator, we can subtract the fractions:
$$ \frac{7}{9} - \frac{3}{9} = \frac{7 - 3}{9} = \frac{4}{9} $$
- Write the final answer
The result of the subtraction is:
$$ \frac{4}{9} $$
The answer is ( \frac{4}{9} ).
