8th Grade Decimal to Fraction Conversion Quizzes

Start with place value: write 0.35 as 35 hundredths, or 35/100, then simplify to 7/20. Once students can handle terminating decimals, show repeating decimals with an algebraic method, such as setting x = 0.333… and subtracting x from 10x to get 9x = 3.

Use a progression of terminating decimals, decimals that require fraction simplification, and repeating decimals. Include tasks that ask students to explain why two forms are equivalent or verify a conversion by dividing the numerator by the denominator.

Common errors include choosing the wrong power-of-ten denominator, forgetting to simplify, and treating a repeating decimal as if it terminates. Ask students to convert the fraction back to a decimal; this quick check exposes most place-value and simplification mistakes.

Assign a quiz as a digital quiz on Wayground or download the printable PDF for paper practice. Every quiz includes a complete answer key, and teachers using paper copies can scan or capture submissions for grading with the Wayground for Teachers app.

Common Core develops this skill from earlier work with place value, equivalent fractions, and rational numbers. By Grade 8, students use fraction-decimal equivalence to compare rational values and prepare for work with rational and irrational numbers.

Give students who need support reduced answer choices or a version with larger text and wider spacing. For advanced learners, create an alternate quiz emphasizing repeating decimals and written justification. Wayground saves student-level accommodations for reuse without changing the default experience for the rest of the class.

Students begin connecting simple decimals and fractions in upper elementary school, then extend the skill to more complex rational numbers; this Grade 8 collection includes both terminating and repeating decimals.
