The Mathematics Knowledge subtest on the ASVAB will include questions that ask you to work with parts of a whole, or fractions. These questions may involve multiplying, dividing, adding, subtracting, and converting fractions, similar to the following practice questions.

Practice questions

  1. Which fractions are not equivalent?

    ASVAB_0201

  2. Given

    ASVAB_0202

    simplify the expression.

    ASVAB_0203

Answers and explanations

  1. The correct answer is Choice (C).

    By finding the lowest common denominator in each set of fractions, you can tell which fractions are equal. In Choice (C), the lowest common denominator is 9. Keep the value of the fractions the same:

    ASVAB_0204

    The two fractions in Choice (C) aren’t equal; all of the other fractions are equal.

  2. The correct answer is Choice (B).

    To divide fractions, you need to flip the fraction you want to divide by; then use the standard multiplication rules to work out the problem and simplify it as much as possible:
