5th Grade Math Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026
By fifth grade children are working with fractions and decimals fluently and meeting volume and the order of operations. It is the bridge to middle school math. This quiz covers the big ideas of the year and lets you retry with new numbers whenever you like.
What this quiz covers
- Adding fractions with different denominators
- Simplifying fractions
- Adding, subtracting and multiplying decimals
- Order of operations with brackets
- Volume of a rectangular box
- Multiplying by powers of ten and converting fractions to decimals
How to prepare
For unlike denominators, find the least common multiple first: for 1/4 + 1/6 use 12. Line up decimal points when adding and subtracting. Remember that brackets come first in the order of operations, then multiplication and division from left to right, then addition and subtraction.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- 2/3 + 3/4 = ?
Show answer
17/12. Use the common denominator 12: 8/12 + 9/12 = 17/12.
- 5.8 − 2.0 = ?
Show answer
3.8. Line up the decimal points: the answer is 3.8.
- 0.4 × 7 = ?
Show answer
2.8. 4 × 7 = 28, then divide by 10: 2.8.
- A box is 4 cm by 4 cm by 5 cm. What is its volume?
Show answer
80 cm³. Volume = 4 × 4 × 5 = 80 cm³.
- Evaluate: (5 + 8) × 4
Show answer
52. Follow the order of operations: brackets first, then multiply and divide left to right, then add and subtract.
