Answer: It will take [tex]\frac{7}{3}[/tex] of an hour to complete the test.
Step-by-step explanation:
We need to convert the mixed number [tex]1\ \frac{1}{3}[/tex] to an improper fraction:
[tex]1\ \frac{1}{3}=\frac{(1*3)+1}{3}= \frac{4}{3} [/tex]
Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:
[tex]\frac{4}{3}+\frac{1}{3}+\frac{2}{3}=\frac{4+1+2}{3}=\frac{7}{3}[/tex]
Therefore, it will take [tex]\frac{7}{3}[/tex] of an hour to complete the test.
