Question 1
What is the sum of the interior angles in a triangle?
Correct Answer:
180
Explanation:
The interior angles of a triangle always add up to 180 degrees. A clear way to see this is to draw a line through the top vertex parallel to the base. The angles at the bottom of the triangle correspond to two angles formed with that parallel line, so those three angles line up along a straight line. A straight line measures 180 degrees, so the three interior angles must sum to 180. For any triangle, whether it’s acute, obtuse, or right-angled, the total of its interior angles is 180 degrees.
Question 2
If 5 workers take 8 hours to finish a job, how many hours would 8 workers take to finish the same job?
Correct Answer:
5
Explanation:
Understanding how work, rate, and time relate. If five workers take eight hours, the total amount of work equals 5 × 8 = 40 units of work (man-hours). The same job requires 40 man-hours in total. With eight workers sharing the workload, time = 40 ÷ 8 = 5 hours. So eight workers would finish in five hours. In general, when everyone works at the same rate, time is inversely proportional to the number of workers. Five hours.
Question 3
What is the result of 15 + (-8)?
Correct Answer:
7
Explanation:
When you add a negative number, you’re essentially subtracting a positive amount. So 15 + (-8) means you start at 15 and move 8 units to the left on the number line, which is the same as 15 − 8. That equals 7. This also follows the rule that when numbers have opposite signs, you subtract the smaller magnitude from the larger and keep the sign of the larger magnitude, which here is the positive 15. So the result is 7. The other results would come from adding the magnitudes (23) or not subtracting at all (15) or taking only the negative part (-8), which aren’t what this expression does.
Question 4
Which is larger, 2/3 or 3/5?
Correct Answer:
2/3
Explanation:
When comparing fractions with different denominators, make the two fractions easier to compare by either cross-multiplying or using a common denominator. Cross-multiplying gives 2/3 and 3/5: 2×5 = 10 and 3×3 = 9. Since 10 is bigger than 9, the first fraction is larger. You can also rewrite with a common denominator: 2/3 = 10/15 and 3/5 = 9/15, so 10/15 is bigger than 9/15. This matches the decimal idea that 2/3 is about 0.666… while 3/5 is 0.6, so 2/3 is the larger value.
Question 5
A test score increases from 70 to 84. What is the percent increase?
Correct Answer:
20%
Explanation:
Percent change is found by comparing the amount of increase to the original value. To find the percent increase from 70 to 84, first find the increase: 84 − 70 = 14. Then divide by the original amount: 14 ÷ 70 = 0.2. Convert to a percent: 0.2 × 100 = 20%. So the score increased by 20%. You can check by applying the percent: 70 × 1.20 = 84. For reference, 15% would give 70 × 1.15 = 80.5, 25% would give 87.5, and 10% would give 77, which don’t match.
