Prepara

Answer 1

11.63 percentage of the earthquakes are minor earthquakes

Step-by-step 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}} * 100`

x =
`(49000)/(421140) * 100`

x =
`0.1165 * 100`

x= 11.63
