Solve the following arithmetic problems: 1.1 Multiplication, 1.2 Division, 1.3 Division, 1.4 Multiplication and Subtraction, 1.5 Ratio problem, 1.6 Distance.

The product is $\boxed{\text{12280352}}$.

The quotient is $\boxed{\text{46824}}$.

Since this is likely intended to be an exact division or a whole number answer, let's recheck the calculation.

If the question implies an exact division, there might be a typo in the number. Assuming it's meant to be calculated as given:

The quotient is approximately $\boxed{\text{2736.12}}$.

The result is $\boxed{\text{10130}}$.

Total parts $= 3 + 4 = 7$

Value of one part $= \frac{\text{R}350}{7} = \text{R}50$

Kenzie's share $= 3 \times \text{R}50 = \text{R}150$

Connor's share $= 4 \times \text{R}50 = \text{R}200$
Kenzie gets $\boxed{\text{R150}}$ and Connor gets $\boxed{\text{R200}}$.

Distance = Speed $\times$ Time.
Given speed $= 60 \text{ km/hour}$ and time $= 8 \text{ hours}$.

We can travel $\boxed{\text{480 km}}$.

Speed = Distance $\div$ Time.
Given distance $= 480 \text{ km}$ and time $= 4 \text{ hours}$.

We are driving at a speed of $\boxed{\text{120 km/hour}}$.

The prime factorization of 24 is $\boxed{2^3 \times 3}$.

2.a

$\frac{2}{5}, \frac{6}{10}, \frac{7}{20}, \frac{1}{2}, \frac{3}{4}$.

The denominators are 5, 10, 20, 2, 4. The LCD is 20.

7, 8, 10, 12, 15.
