Answer 1

Answer:

11.63 percentage of the earthquakes  are minor earthquakes

Explanation:

Given:

The number of earthquakes that that occur  annually = 421,140

The number of minor earthquakes that that occur annually  = 49,000

To Find:

Percentage of minor earthquakes =?

Solution:

let the percentage of minor earthquake be x

then

x = $\frac{\text{ number of minor earthquake}}{\text{total number of earthquake}} \times 100$

x = $\frac{49000}{421140} \times 100$

x =$0.1165 \times 100$

x= 11.63
