Answer:
65%
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.
