1. Arithmetic (Fractions)
Question: What is the result of: 3/4 + 2/3?
Solution:
Find the common denominator (LCM of 4 and 3 is 12):
3/4 = 9/12
2/3 = 8/12
Add the fractions:
9/12 + 8/12 = 17/12 = 1 5/12
Answer: 1 5/12
2. Arithmetic (Percents)
Question: 20% of what number is 36?
Solution:
Let x be the unknown number:
0.20x = 36
x = 36 ÷ 0.20 = 180
Answer: 180
3. Quantitative Reasoning (Algebraic Expressions)
Question: Simplify: 3(x - 2) + 4(2x + 1)
Solution:
Distribute:
= 3x - 6 + 8x + 4
Combine like terms:
= 11x - 2
Answer: 11x - 2
4. Quantitative Reasoning (Solving Equations)
Question: Solve for x: 2x + 5 = 3x - 7
Solution:
Subtract 2x from both sides:
5=x-7
Add 7 to both sides:
x = 12
Answer: 12
,5. Advanced Algebra (Exponents)
Question: Simplify: (2x³)²
Solution:
Apply exponent rules:
= 2² × x⁶ = 4x⁶
Answer: 4x⁶
6. Advanced Algebra (Inequalities)
Question: Solve: 5 - 2x < 1
Solution:
Subtract 5 from both sides:
-2x < -4
Divide by -2 (reverse the inequality):
x>2
Answer: x > 2

Multiply:
5.7 × 0.4 = 2.28
Answer: 2.28
12. Arithmetic (Order of Operations)
Question: What is the result of: 6 + 2 × (5 – 3)²?
Solution:
Step 1: Parentheses → (5 – 3) = 2
Step 2: Exponent → 2² = 4
Step 3: Multiply → 2 × 4 = 8
Step 4: Add → 6 + 8 = 14
Answer: 14
