In March of 2017, 12 of the top 100 women's tennis players in the world were from the United States. What percent of
the tennis players were HOT from the United States?

The percent of the tennis players NOT from the United States is:

88%.

Explanation:

a) Data and Calculations:"

Number of top 100 women's tennis players in the world = 100

The number of this from the United States = 12

This represents 12% (12/100) of the population of top tennis players in the world.

Therefore, the number of top tennis players in the world that is not from the United States = 88 (100 - 12)

This number represents 88% (88/100) of the population of top tennis players in the world.

b) The question requires the expression of the numbers into two groups: those from the United States (12) and the remaining 88 (100 - 12) NOT from the United States.  Once this is done, the resulting figures are expressed as percentages of the total, and the rest is the required answer.
