Let be "x" the number of hours of your work week you spend stocking shelves.
According to the information provided in the exercise, you work a total of 20 hours each week and you spend 3/5 of that time stocking shelves.
You can write that fraction as a decimal number by dividing the numerator by de denominator:
![\frac{3}{5}=0.6](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%3D0.6)
Then, to find the value of "x", you only need to multiply the total hours you work each week by 0.6.
Therefore, the result is:
![\begin{gathered} x=(20hours)(0.6) \\ x=12\text{hours} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%2820hours%29%280.6%29%20%5C%5C%20x%3D12%5Ctext%7Bhours%7D%20%5Cend%7Bgathered%7D)
You spend 12 hours of your work week stocking shelves.
