Correct Answer: D
Calculated as: (1/2) * (1/4) * (1/5) * 200 = (1/40) * 200 = 5.
Q113.What is 3/10 divided by 1 4/5?
Correct Answer: B
3/10 ÷ 9/5 = 3/10 * 5/9 = (3*5)/(10*9) = 15/90 = 1/6.
Q114.What is the value of 2 - 1/3?
Correct Answer: A
Convert to common denominator: 2 = 6/3. Then: 6/3 - 1/3 = 5/3.
Q115.Evaluate: 2 2/3 × 5/14
Correct Answer: A
Convert mixed fraction: 2 2/3 = 8/3. Multiply: (8/3) * (5/14) = 40/42 = 20/21.
Q116.What is the value of the division: (9/2) ÷ (81/8)?
Correct Answer: A
(9/2) ÷ (81/8) = (9/2) * (8/81) = (9*8) / (2*81) = 72 / 162 = 4/9.
Q117.What is the next prime number after 5?
Correct Answer: B
The prime numbers after 5 are: 7, 11, 13... So, the next prime number after 5 is 7.
Q118.Round 3.864 to the nearest tenth.
