To add the fraction \( \frac{7}{15} \) and the whole number \( 15 \), we first need to express \( 15 \) as a fraction. We can write \( 15 \) as \( \frac{15}{1} \).
Now, we need a common denominator to add the two fractions. The least common denominator (LCD) of \( 15 \) and \( 1 \) is \( 15 \).
We'll convert \( 15 \) to a fraction with a denominator of \( 15 \):
\[ 15 = \frac{15 \times 15}{1 \times 15} = \frac{225}{15} \]
Now, we can add \( \frac{7}{15} \) and \( \frac{225}{15} \):
\[ \frac{7}{15} + \frac{225}{15} = \frac{7 + 225}{15} = \frac{232}{15} \]
Thus, \( \frac{7}{15} + 15 \) as a fraction is \( \frac{232}{15} \).
