Answer 1

Minor earthquakes occurred in the country in the last​ year were 2326.

Explanation:

Given:

In the last​ year, a total of 2727 earthquakes occurred in the country.

Of​ these, 85.3 % were minor tremors with magnitudes of 3.9 or less on the Richter scale.

Now, to find the minor earthquakes occured in the country last year.

Total earthquakes occurred in the country = 2727.

The percent of minor earthquakes = 85.3%.

Now, to get the number of minor earthquakes:

85.3% of 2727.

`=(85.3)/(100) * 2727.`

`=(232613.1)/(100)`

`=2326.131`

The number of minor earthquakes nearest whole number = 2326.

Therefore, minor earthquakes occurred in the country in the last​ year were 2326.
