## Answer:

**1. B**

1.8 is the closest. 2 - 1.8 = 0.2, while 2.4 -2 = 0,4. 2 - 1 = 1, and 2 - 0.3 = 1.7. The smallest difference is 0.2, so 1.8 is the correct answer.

**2. A.**

Just divide 10,000 by 4 and you get 2,500.

**3. C.**

The least common multiple of a group of numbers is the last whole number (greater than 0) that is a multiple of all of the numbers. The least common multiple of 3,4 and 18 is 36 (3 x 12, 4 x 9, 2 x 18).
