Practice for family 3. Quizzes 8 to 12 explain each of these skills; this sheet is for doing them until they are quick. 176 problems in four parts, each section starting with its plainest version.
- Simplify every answer. The test's answer choices are almost always in simplest form.
- Estimate first. 1⁄2 + 1⁄3 is a little more than 1⁄2, so an answer of 2⁄5 cannot be right.
- Work in pencil, one section at a sitting.
Part One
Naming fractions
The same amount can have many names. These sections are about finding the simplest one, and moving between the forms.
1.Simplifying
Divide the top and the bottom by the same number until nothing but 1 divides both.
Simplify each fraction.
- 1.Simplify 5⁄10
- 2.Simplify 6⁄12
- 3.Simplify 6⁄18
- 4.Simplify 18⁄20
- 5.Simplify 12⁄20

- 13.Simplify 9⁄63
- 14.Simplify 16⁄88
2.Equivalent fractions
Whatever you multiply the bottom by, multiply the top by the same.
Find the missing number.
- 15.1⁄5 = 6⁄?
- 16.1⁄8 = 4⁄?
- 17.1⁄2 = ?⁄8
- 18.2⁄9 = 6⁄?

3.Improper fractions to mixed numbers
Divide the top by the bottom. The whole number is how many times it goes; the remainder goes over the same bottom.
Write each as a mixed number.
- 29.Write 5⁄2 as a mixed number

4.Mixed numbers to improper fractions
Multiply the whole number by the bottom, add the top, and keep the bottom.
Write each as an improper fraction.
- 39.Write 2 1⁄2 as an improper fraction
- 40.Write 7 1⁄5 as an improper fraction

- 47.Write 2 7⁄10 as an improper fraction
- 48.Write 3 3⁄10 as an improper fraction
5.Which is larger?
Put both over the same bottom, then compare the tops. Or cross-multiply: the larger product sits above the larger fraction.
Write >, <, or = in the box.
