You worked theses hours this week: 1 1/2 , 2 3/4, 3 3/4, 5 1/2 how many hours did you work?
a. 15
b. 17
c. 17 1/2
d. 17 1/4

13.5 hours.

I got the answer by simply adding up the integers to start with.

Integers = 1, 2, 3 and 5.

The integers added up equal to 11.

Next we add up the remaining fractions.

Fractions = 1/2, 3/4, 3/4 and 1/2.

We can add up 1/2 and 1/2 to equal 1, and 3/4 and 3/4 to make 1.5.

1 + 1.5 = 2.5          

Finally, we add up the answer for the integers and the fractions together, (11 + 2.5) which equals 13.5.

Our answer is 13.5 hours.      

(Not sure why the answer isn't in the choices)                          

to rewrite a literal equation you may need to divide by a number, or by a variable.
