Ralph spends 15 1/3 hours per month playing tennis. How many hours does he play tennis in a year?
a) 164 b)184 c)182 2/3 d)164 1/3
I'm thinking the answer is B
in one month he plays $\displaystyle 15\frac{1}{3}$ hours of tennis, which is equal to $\displaystyle \frac{46}{3}$ hours.Originally Posted by Angel King
There are twelve months in a year, therefore you multiply $\displaystyle \frac{46}{3}$ by 12 to get $\displaystyle \frac{46}{3} \times \frac{12}{1}=\frac{46\times12}{3\times1}=\frac{552 }{3}=184$, therefore the answer is b. good job.
