Pre-Algebra questions with worked answers
These 8 questions are printed in full on this page and are drawn across all 5 course units. Nothing here is generated on the fly. Cover the options, solve each one on paper, and only then open the worked answer to compare your method with the one shown.
Question 1: Work out -7 + 12 - (-5).
Pre-Algebra · Integers and rational numbers
- 10
- 0
- -10
- 24
Show the worked answer
- Subtracting a negative number is the same as adding, so -(-5) becomes +5.
- The expression is now -7 + 12 + 5.
- -7 + 12 = 5.
- 5 + 5 = 10, so the answer is 10.
Answer: 10
Question 2: Which of these numbers is the greatest: -3/4, -0.7, -5/8, or -0.71?
Pre-Algebra · Integers and rational numbers
- -5/8
- -0.7
- -0.71
- -3/4
Show the worked answer
- Write every number as a decimal so they can be compared directly.
- -3/4 = -0.75 and -5/8 = -0.625.
- The four values are -0.75, -0.7, -0.625, and -0.71.
- On a number line the greatest negative number is the one closest to zero, and that is -0.625, which is -5/8.
Answer: -5/8
Question 3: Three pounds of apples cost $7.50. At the same rate, what do 8 pounds cost?
Pre-Algebra · Ratios and proportions
- $20.00
- $18.75
- $22.50
- $15.00
Show the worked answer
- Find the price for one pound first. That is the unit rate.
- 7.50 / 3 = 2.50, so apples cost $2.50 per pound.
- Eight pounds cost 8 x 2.50.
- 8 x 2.50 = 20, so 8 pounds cost $20.00.
Answer: $20.00
Question 4: On a map, 1 cm stands for 15 km. Two towns are 4.5 cm apart on the map. How far apart are they in real life?
Pre-Algebra · Ratios and proportions
- 67.5 km
- 19.5 km
- 3.3 km
- 60 km
Show the worked answer
- Every 1 cm on the map is 15 km on the ground, so multiply by 15.
- 4.5 x 15 is the real distance in kilometers.
- 4 x 15 = 60 and 0.5 x 15 = 7.5.
- 60 + 7.5 = 67.5, so the towns are 67.5 km apart.
Answer: 67.5 km
Question 5: Evaluate 5x - 3y when x = -2 and y = 4.
Pre-Algebra · Expressions and variables
- -22
- -2
- 22
- 2
Show the worked answer
- Replace each letter with its value: 5(-2) - 3(4).
- 5 x (-2) = -10.
- 3 x 4 = 12, and that amount is subtracted.
- -10 - 12 = -22.
Answer: -22
Question 6: A line passes through the points (2, 3) and (6, 11). What is its slope?
Pre-Algebra · Linear relationships
- 2
- 1/2
- 4
- 8
Show the worked answer
- Slope is the change in y divided by the change in x.
- The y values change by 11 - 3 = 8.
- The x values change by 6 - 2 = 4.
- 8 / 4 = 2, so the slope is 2.
Answer: 2
Question 7: Solve 4x + 7 = 31 for x.
Pre-Algebra · Linear relationships
- 6
- 9.5
- 24
- 7
Show the worked answer
- Undo the addition first. Subtract 7 from both sides.
- 4x + 7 - 7 = 31 - 7 gives 4x = 24.
- Now undo the multiplication. Divide both sides by 4.
- 24 / 4 = 6, so x = 6. Check: 4(6) + 7 = 31.
Answer: 6
Question 8: A rectangle has a perimeter of 34 cm and a length of 11 cm. What is its area?
Pre-Algebra · Geometry foundations
- 66 square cm
- 374 square cm
- 132 square cm
- 72 square cm
Show the worked answer
- Perimeter counts each length and each width twice: 2(length) + 2(width) = 34.
- The two lengths use 2 x 11 = 22 cm of the perimeter.
- That leaves 34 - 22 = 12 cm for the two widths, so each width is 12 / 2 = 6 cm.
- Area = length x width = 11 x 6 = 66 square cm.
Answer: 66 square cm

Use this map after marking your work. If two misses share a unit, review that unit before starting a generated set.
How the generated Pre-Algebra sets are created
The 8 questions above are fixed and checked. The generator at the top of the page is different: it writes fresh questions with AI from the course and unit information shown here, then the application checks each one for a complete prompt, four choices, one keyed answer, and an explanation. Generated questions are original practice—not official or released exam questions—and AI can still make mathematical mistakes. Verify a disputed answer with the stated method, your course materials, or the MathGPT solver, and follow the site's academic-integrity guidance.
Questions about this Pre-Algebra practice page
What does this page cover?
It covers all 5 Pre-Algebra units listed above. Choose one unit for focused work, or mixed review to test method selection, and switch to test mode when you want all units mixed under time.
When can I see correct answers and explanations?
The 8 printed questions on this page keep their worked answers behind a toggle, so you can check any one of them straight away. In the generator above, practice mode explains each question as soon as you answer it, while test mode holds every explanation until you submit.
What should I do with a missed question?
Classify the miss as a definition, setup, calculation, interpretation, or timing error. Re-solve it from a blank page, then use the MathGPT tutor for a hint or method check.
