The Closure Property states that when you perform an operation (like addition, subtraction, multiplication, or division) on two elements of a certain set, the result will also be an element of that same set.
In this case, you're multiplying two numbers: \( \frac{4}{5} \) (a rational number) and \( 15 \) (an integer).
The product is calculated as follows:
\[ \frac{4}{5} \times 15 = \frac{4 \times 15}{5} = \frac{60}{5} = 12 \]
The result, \( 12 \), is an integer.
Since both \( \frac{4}{5} \) and \( 15 \) are rational numbers, and the product of two rational numbers is also a rational number, we can conclude that:
- The product \( 12 \) is an integer, and therefore also a rational number.
So, the product of \( \frac{4}{5} \) and \( 15 \) is a rational number.
