Combine the following math problems into one homework assignment: 1. Write 3690 in words. 2. How many centimeters in a meter? 3. Find LCM of 2 and 3. 4. List 6 prime numbers. 5. Convert 4 2/8 to impro

Multiples of 2: $2, 4, \mathbf{6}, 8, 10, \dots$  
Multiples of 3: $3, \mathbf{6}, 9, 12, \dots$

The smallest number that appears in both lists is 6.
$$
\text{L.C.M}(2, 3) = \boxed{6}
$$
Your answer is correct.

$$
4 \times 8 = 32
$$

$$
32 + 2 = 34
$$

$$
4\frac{2}{8} = \boxed{\frac{34}{8}}
$$
Your answer is correct.

$$
1 \text{ Kg} = 1000 \text{ g}
$$

$$
8 \text{ Kg} \times 1000 \frac{\text{g}}{\text{Kg}} = \boxed{8000 \text{ g}}
$$

$$
325 \text{ litres} + 85 \text{ litres} = \boxed{410 \text{ litres}}
$$
Your answer is correct.
