Steps to Solve

  1. 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.

  1. 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:

$$ \frac{1}{3} = \frac{1 \times 3}{3 \times 3} = \frac{3}{9} $$

  1. Subtract the fractions

Now that we have the same denominator, we can subtract the fractions:

$$ \frac{7}{9} - \frac{3}{9} = \frac{7 - 3}{9} = \frac{4}{9} $$

  1. Write the final answer

The result of the subtraction is:

$$ \frac{4}{9} $$

The answer is ( \frac{4}{9} ).

More Information

The result ( \frac{4}{9} ) shows that when you subtract ( \frac{1}{3} ) from ( \frac{7}{9} ), you effectively take away ( \frac{3}{9} ) from ( \frac{7}{9} ).
