In order to determine the time for research, calculate one quarter of the time spend in the project of the company.
Express the time for the project as a normal fraction, as follow:
5 1/3 = 5/1 + 1/3 = (15 + 1)/3 = 16/3
Next, multiply 1/4 (one quarter) by the previous fraction 16/3:
(1/4)·(16/3) = 16/12
simplify the previous fraction:
16/12 = 4/3
as a mixed number the previous result is:
4/3 = 1 1/3
