=12 if we are talking in terms of basic operations.
Hello there! We can answer through division here, given there are 12 donuts in a dozen:
46.2 divided by 12 gives us 3.85 dozens. However, there cannot be a fraction of a dozen in representation of a whole. Rounding to the nearest dozen, we will find that there are about 4 dozens in 46.2 donuts.
For there to be a value of 46.2 donuts, there had to have been more donuts to start with in the dozen. Therefore, we would round up. If there were 3 dozens, that would give us 36 donuts, which would not make sense because there are 46.2 present.
Hope this helps!
So to set up this equation, you have to do
Time1*Workers1=Time2*Workers2
In this case, Time1=24 days, Workers1=15 electricians, and Workers2=18 electricians, and we have to solve for Time2
Thus we get 15*24=18*Time2
Time2=15*24/18=20 days
