Question

In the last​ year, a total of 15,456 earthquakes occurred in a country. Of​ these 88.7% were minor tremors with magnitudes of 4.9 or less on the Richter scale. How many minor earthquakes occurred in the country in the last​ year?

(Round to the nearest whole​ number.)

Answer 1

88.7% means you need to multiply by 88.7 and divide by 100 (or simplified multiply by 0.887)

Therefore $15, 456 \times0.887$ is the number of minor quakes

Which is rounded up to 13709
