Minor earthquakes occurred in the country in the last year were<u> 2326</u>.
Step-by-step 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.
<em>Total earthquakes occurred in the country = 2727.</em>
<em>The percent of minor earthquakes = 85.3%</em>.
Now, to get the number of minor earthquakes:
85.3% of 2727.
<em>The number of minor earthquakes nearest whole number = 2326.</em>
Therefore, minor earthquakes occurred in the country in the last year were 2326.
