Answer 1

15836

Explanation:

Formula

Minor Earthquakes = (%) * Total Earthquakes.

Givens

Minor Earthquakes = ??

% = 89.6

Total Earthquakes = 17674

Solution

Minor Earthquakes = 89.6 / 100 * 17674

Minor Earthquakes = 1583590.4/100

Minor Earthquakes = 15836

Answer 2

Answer: There are 14940 minor earthquakes occurred in the world in 2014.

Explanation:

Since we have given that

Number of earthquakes occurred world wide = 16674

Percentage of minor tremors with magnitude of 4.9 or less = 89.6%

So, Number of minor earthquakes occurred in the world in 2014 is given by

`(89.6)/(100)* 16674\\\\=0.896* 16674\\\\=14939.90`

Hence, there are 14940 minor earthquakes occurred in the world in 2014.
