Calculate the ratio of the mean free path of molecules of two gases in the ratio of the numbers density per `cm^(3)` of the gases is `5:3` and the ratio of the diameters of the molecules of the gases is `4:5`

Explanation

To calculate the ratio of the mean free path of molecules of two gases, we will follow these steps:

### Step 1: Understand the given ratios
We are given:
- The ratio of number densities (n1:n2) = 5:3
- The ratio of diameters (d1:d2) = 4:5

### Step 2: Express the ratios mathematically
