To find how many ounces are in \( \frac{12}{15} \) of a 10-ounce block of cheese, you can multiply the fraction by the total weight of the cheese:
\[ \frac{12}{15} \times 10 \text{ ounces} \]
First, simplify the fraction \( \frac{12}{15} \):
\[ \frac{12}{15} = \frac{4}{5} \]
Now, multiply \( \frac{4}{5} \) by 10 ounces:
\[ \frac{4}{5} \times 10 = \frac{40}{5} = 8 \text{ ounces} \]
So, \( \frac{12}{15} \) of a 10-ounce block of cheese is 8 ounces.
