24
18
12
8
The smallest number that both 4 and 6 divide into evenly is 12. Finding the LCM is a crucial skill when adding fractions with different denominators.
If a rectangle has a length of 8 and a width of 3, what is its area?
24
11
22
32
The area of a rectangle is found by multiplying its length and width; hence, 8 × 3 equals 24. This formula is fundamental in geometry.
Which prime number lies between 20 and 30?
23
21
27
25
Of the options provided, 23 is the only prime number between 20 and 30. Recognizing prime numbers aids in deeper number theory concepts.

If a car travels 60 km in 1 hour, how far will it travel in 3 hours at the same speed?
120 km
180 km
150 km
200 km
Traveling 60 km per hour for 3 hours results in 180 km. This problem applies the direct relationship between speed, time, and distance.
What is the slope of a line that rises 4 units for every 2 units it runs?
1/2
4
2
6
The slope is determined by dividing the rise by the run: 4/2 equals 2. Understanding slope is essential in analyzing linear equations.
What is 45% of 200?
90
85
80
100
Calculating 45% of 200 involves converting 45% to 0.45 and multiplying by 200, which results in 90. This exercise reinforces percentage calculations.
A triangle has two angles of 45° each. What is the measure of the third angle?
90°
100°
45°
60°
The sum of angles in any triangle is 180°. Subtracting the two 45° angles (totaling 90°) from 180° leaves a third angle of 90°.
Hard
Solve for x: 3(x - 2) = 2x + 4.
12
6
10
8
Distributing 3 gives 3x - 6, and setting the equation 3x - 6 = 2x + 4 leads to x = 10 after isolating the variable. This reinforces solving linear equations with variables on both sides.
A circle has a radius of 7. What is the approximate area of the circle using π ≈ 3.14?
153.86
49
44
200
The area of a circle is calculated as πr², so 3.14 × 7² equals about 153.86. This problem applies the formula for the area of a circle and approximates π.
If f(x) = 2x² - 3x + 1, what is f(3)?
9
8
12
10
Substituting x = 3 into the function gives 2(9) - 3(3) + 1, which simplifies to 18 - 9 + 1 = 10. Evaluating functions accurately is a key algebraic skill.
The sides of a right triangle are in the ratio 3:4:5. If the shortest side measures 9, what is the length of the hypotenuse?
15
20
12
18
A ratio of 3:4:5 implies a scaling factor of 9/3 = 3, so the hypotenuse, being 5 parts, equals 5 × 3 = 15. This problem combines proportional reasoning with geometry.
Simplify the expression: (2/3) ÷ (4/5).
8/15
10/7
3/2
5/6
Dividing by a fraction involves multiplying by its reciprocal; (2/3) ÷ (4/5) becomes (2/3) × (5/4) which simplifies to 10/12 or 5/6. Mastering fraction operations is key in advanced math.
