3. a _____________ of a number is a product of the number and any nonzero whole number.

Explanation:

1. Benchmark fractions are common, easy-to-use fractions (like $\frac{1}{2}$, $\frac{1}{4}$) that are used to estimate sums of other fractions by replacing the original addends.
2. Equivalent fractions have the same value, and you create them by multiplying both the numerator and denominator of a fraction by the same non-zero number.
3. A multiple of a number is the product of that number and any non-zero whole number.

Answer:

1. benchmark fractions
