Naddika [18.5K]

Answer:

The number of desktop internet users are 3 times more than the number of mobile internet users.

Step-by-step explanation:

We are given the following in the question:

Number of mobile internet users = 400,000,000

$400,000,000 = 4\times 10^{8}$

Number of desktop internet user =

$1.2 \times 10^9$

Comparison of values:

$=\dfrac{\text{Number of desktop internet user}}{\text{Number of mobile interet user}}\\\\=\dfrac{1.2\times 10^9}{4\times 10^8}\\\\=0.3\times 10\\=3$

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.
