One out of 5 of a group of students took a math test, 28% of the same group took a science test and the rest took a history test.

One out of 5 of a group of students took a math test, 28% of the same group took a science test and the rest took a history test. If each student took one test only, what percent of students took a history test?

Solutions

Expert Solution

One out of 5 may be written as a fraction equal to

1/5

and in percent as

20%

The total number of students in percent is 100%. Since 20% took math and 28% took science, the percent of those who took history is

100% - 20% - 28% = 52%

52%
