Answer 2

I can help you with math problems. The answer to your question is 4.5. Here is how you can solve it:

- To multiply a fraction by a whole number, you can multiply the numerator by the whole number and keep the denominator the same. For example, 3/10 * 15 = (3 * 15) / 10 = 45 / 10. - To simplify a fraction, you can divide both the numerator and the denominator by a common factor. For example, 45 / 10 = (45 / 5) / (10 / 5) = 9 / 2. - To convert an improper fraction to a mixed number, you can divide the numerator by the denominator and write the remainder as a fraction. For example, 9 / 2 = 4 + 1 / 2 = 4 1/2.

So, 3/10 * 15 = 4 1/2 or 4.5 in decimal form. You can also use [this online tool](https://mathsolver.microsoft.com/en/solve-problem/15) to check your answers and see the steps. I hope this helps.
