A laboratory technician completes 80 tests in one day. If 52 of these tests were completed in the morning, what percent of the tests were completed in the morning?

65%

Step-by-step explanation:

Given that:

Number of test completed per day = 80

Number of tests completed in the morning = 52

Percentage of tests completed in the morning ;

[(Number of test completed in the morning) / (total number of test completed per day)] * 100%

(52 / 80) * 100%

0.65 * 100%

= 65%

Hence, 65% of the total tests completed per day is completed in the morning.
