Answer:
8.3%
Step-by-step explanation:
A worker is paid from noon to 3 pm. So the worker works for 3 hours.
To find the percentage, we need to have the same units.
To do this, convert 3 hours to minutes and get 180 minutes.
We can now write a fraction (break minutes/total work time) to find the percent of the number of minutes in their break as a part of their whole paid shift.
This fraction is 15/180.
We can now simplify this fraction to 1/12.
Then convert into decimal form and get 0.0833.
Finally convert this decimal into a percentage by multiplying by 100 and get 8.3%
Definitely the third one
