4/5 + 5/15 = [__] [__]/[__]

1 answer

To add the fractions \( \frac{4}{5} + \frac{5}{15} \), we first need to find a common denominator. The least common multiple of 5 and 15 is 15.

Now we will convert \( \frac{4}{5} \) to a fraction with a denominator of 15:

\[ \frac{4}{5} = \frac{4 \times 3}{5 \times 3} = \frac{12}{15} \]

Now we can add \( \frac{12}{15} \) and \( \frac{5}{15} \):

\[ \frac{12}{15} + \frac{5}{15} = \frac{12 + 5}{15} = \frac{17}{15} \]

Thus, we can express the answer as:

\[ \frac{17}{15} \]

In the format requested: [17] [17]/[15].

So the answer is:

\[ 17 \] \[ 17 \]/\[ 15 \]
