Of the 1543 tornadoes that occurred in the United States during 2010, 27.7% occurred during the month of June. How many tornadoes occurred in the United States during June. 2010? Round to the nearest whole.

Answer 1

Set up the following ratio:

\[\frac{ x }{ 1543 } = \frac{ 27.7 }{ 100}\]

Cross multiply:

100x = 42741.1

Divide by 100 to find x:

x = 427.411

rounded to the nearest whole number is 427 tornadoes.
