Question

the closure property implies that the product of 4/5 and 15 is what type of number a,zero b, an integer,c,irrational,d,rational

Answer 1

To determine the type of number that the product of \( \frac{4}{5} \) and \( 15 \) is, we first calculate the product:

\[
\frac{4}{5} \times 15 = \frac{4 \times 15}{5} = \frac{60}{5} = 12
\]

Now, let's identify what type of number \( 12 \) is.

- **A) Zero**: \( 12 \) is not zero.
- **B) An integer**: \( 12 \) is an integer.
- **C) Irrational**: \( 12 \) is not irrational; it can be expressed as a fraction (\( \frac{12}{1} \)).
- **D) Rational**: \( 12 \) is a rational number, as it can be expressed as a fraction of two integers.

Since \( 12 \) is an integer and also a rational number, the correct answers would be **B) an integer** and **D) rational**.

However, if you are looking for just one answer, the most straightforward answer is **B) an integer**.
