To multiply the expression \( (5h - 15) \) by \( \frac{1}{5} \), you can distribute \( \frac{1}{5} \) to both terms inside the parentheses:
\[ (5h - 15) \cdot \frac{1}{5} = 5h \cdot \frac{1}{5} - 15 \cdot \frac{1}{5} \]
Now, calculate each term:
-
For the first term: \[ 5h \cdot \frac{1}{5} = h \]
-
For the second term: \[ -15 \cdot \frac{1}{5} = -3 \]
Now combine the results:
\[ h - 3 \]
So, the result of \( (5h - 15) \) multiplied by \( \frac{1}{5} \) is:
\[ h - 3 \]
