Question

5 sixths plus 7 nignths

Answer 1

To add the fractions \( \frac{5}{6} \) and \( \frac{7}{9} \), we need a common denominator. The least common denominator (LCD) of 6 and 9 is 18.

Now, we can convert each fraction to have the denominator of 18:

1. Convert \( \frac{5}{6} \):
\[
\frac{5}{6} = \frac{5 \times 3}{6 \times 3} = \frac{15}{18}
\]

2. Convert \( \frac{7}{9} \):
\[
\frac{7}{9} = \frac{7 \times 2}{9 \times 2} = \frac{14}{18}
\]

Now we can add the two fractions:
\[
\frac{15}{18} + \frac{14}{18} = \frac{15 + 14}{18} = \frac{29}{18}
\]

The result is \( \frac{29}{18} \), which is an improper fraction. It can also be expressed as a mixed number:
\[
\frac{29}{18} = 1 \frac{11}{18}
\]

So, the final answer is:
\[
\frac{29}{18} \text{ or } 1 \frac{11}{18}
\]
