6th Grade Math Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026
Sixth grade introduces ratios, negative numbers, exponents and statistics, and it is often the first year students are asked to reason instead of just calculate. The quiz spans those new topics and reinforces GCF and LCM from earlier grades.
What this quiz covers
- Simplifying ratios and solving simple proportions
- Finding a percent of a number
- Adding integers, including negatives
- Evaluating whole-number exponents
- Mean and median of a data set
- Area of a triangle, GCF and LCM
How to prepare
Draw a number line for negative numbers and move left or right. For ratios, think “multiply or divide both parts by the same number”. For the mean, add all the values and divide by how many there are; for the median, always sort first.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- Simplify the ratio 15 : 21.
Show answer
5 : 7. Divide both parts by 3: 5 : 7.
- 2 : 6 = 8 : x. What is x?
Show answer
24. Multiply both parts of 2 : 6 by 4: x = 6 × 4 = 24.
- What is 20% of 240?
Show answer
48. 20% = 20/100, so 240 × 0.2 = 48.
- -6 + (-5) = ?
Show answer
-11. Combine -6 and -5: the result is -11.
- 3³ = ?
Show answer
27. 3³ = 3 × 3 × 3 = 27.
