• A. 36
• B. 144
• C. 288
• D. 72Computer Online Quiz

Explanation: The denominator is 24 × 0.75 = 18. Therefore 1296 ÷ 18 = 72. The likely mistake is 36, which comes from dividing by 36 after treating 0.75…

• A. 651
• B. 361
• C. 100
• D. 95

• A. 0.1
• B. 0.2
• C. 0.3
• D. 0.4

Explanation: Square the decimals first: 0.9 × 0.9 = 0.81 and 0.8 × 0.8 = 0.64. Their difference is 0.17, and 0.17 ÷ 1.7 = 0.1, so option a is correct.

• A. 182/3
• B. 1831/54
• C. 18
• D. 201/2

Explanation: Treating the terms as mixed numbers, use denominator 54: 12 13/18 = 687/54, 16 11/27 = 886/54, and 10 5/9 = 570/54.

• A. 3
• B. 2
• C. 4
• D. 6Enrolling In Online Certification Courses

Explanation: Multiplication and division have equal priority, so work from left to right: 5 x 5 ÷ 5 + 5 ÷ 5 = 25 ÷ 5 + 1 = 5 + 1 = 6.

• A. 12
• B. 18
• C. 20
• D. 30

Explanation: Evaluate multiplication and division from left to right: 36 x 48 ÷ 64 = 36 x 3/4 = 27, and 36 ÷ 12 = 3.

• A. 20
• B. 8
• C. 10
• D. 15

Explanation: Interpret the radical as √(144/121) = 12/11. Since 2/3 + 1/4 = 11/12, their product is 1; the braces then give 4 x (1 + 23) ÷ 12 + 5 = 8 +…

• A. 9/8
• B. 3/10
• C. 3/5
• D. 3/8

Explanation: Apply multiplication before addition and subtraction: the numerator is 6 - (2 x 3) + 6 = 6, and the denominator is 2 + (6 x 3) - 4 = 16.

• A. 4 9/11
• B. 37
• C. 47
• D. 74

Explanation: Convert the mixed numbers: 5 1/2 = 11/2 and 7 5/6 = 47/6. Then 2/3 x 11/2 x 2 x 47/6 x 9/11 simplifies by cancellation to 47, so option c…

• A. 3 9/13
• B. 1 9/11
• C. 2 11/72
• D. None of these

Explanation: Convert the mixed numbers and use denominator 72: 3 7/8 - 2 1/3 + 1 7/9 = 31/8 - 7/3 + 16/9 = 239/72.

• A. x = 4, y = 8
• B. x = 4, y = 4
• C. x = 2, y = 4
• D. x = 8, y = 4

Explanation: Test the mixed-number equation using the proposed values x = 8 and y = 4: (3 + 1/8)(4 + 2/5) = 25/8 x 22/5 = 550/40 = 55/4 = 13 3/4.
