7/9 + 5/18 = [__] [__]/[__]

1 answer

To add the fractions \( \frac{7}{9} \) and \( \frac{5}{18} \), we first need a common denominator. The least common multiple of 9 and 18 is 18.

Now, we can rewrite \( \frac{7}{9} \) with 18 as the denominator:

\[ \frac{7}{9} = \frac{7 \times 2}{9 \times 2} = \frac{14}{18} \]

Next, we add \( \frac{14}{18} \) and \( \frac{5}{18} \):

\[ \frac{14}{18} + \frac{5}{18} = \frac{14 + 5}{18} = \frac{19}{18} \]

Thus, \( \frac{19}{18} \) can be expressed as:

\[ 1 \frac{1}{18} \]

So, the final answer in the requested format is:

\[ 1\ \ 1\ /\ 18 \]
