Sample Test 2 Questions and Detailed Answer Key Explanations

Question 1: Basic Arithmetic

Calculate: 75 ÷ 5 + 8 × 3

Answer: 75 ÷ 5 + 8 × 3 = 15 + 24 = 39

Explanation: Follow order of operations (PEMDAS): division and multiplication first, then addition. 75 ÷ 5 = 15, 8 × 3 = 24, sum = 39.

Question 2: Algebraic Equation

Solve for x: 3x + 7 = 22

Answer: x = 5

Explanation: Subtract 7 from both sides: 3x = 15, then divide both sides by 3: x = 5.

Question 3: Percentage Calculation

What is 20% of 150?

Answer: 30

Explanation: Convert percentage to decimal (0.20) and multiply: 0.20 × 150 = 30.

Question 4: Ratio and Proportion

If the ratio of apples to oranges is 3:4 and there are 12 apples, how many oranges are there?

Answer: 16 oranges

Explanation: Set up proportion: 3/4 = 12/x. Cross-multiplied: 3x = 48, so x = 16.

Question 5: Units Conversion

Convert 10 inches to centimeters. (Use 1 inch = 2.54 cm)

Answer: 25.4 cm

Explanation: Multiply inches by conversion factor: 10 × 2.54 = 25.4 cm.

Strategies for Using the Answer Key to Improve Calculations Skills
