Answer:
Sam worked
hours that day (fractional answer)
Explanation:
The total number of hours Sam worked is the sum of all the three hours given.
Let's add the first 2 using LCM and then add that result with the last.
Firstly:
![(1)/(5)+(2)/(3)\\=(1(3)+2(5))/(15)\\=(13)/(15)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/495qm78t2xlk2lstj4iuotym55zg4yisij.png)
Now,
![(13)/(15)+(1)/(2)\\=(13(2)+1(15))/(30)\\=(41)/(30)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1djy7cqa6dslp16fce89idtvqoigtiguur.png)
The hours worked by Sam is 41/30 hours (fractional answer).
