Dividing by 100 is the same as multiplying by 1/100 or 0.01, because when you divide by a fraction, in this case 100/1, you actually multiply by the reciprocal, which would be 1/100. For example 4/100 = 4 x 1/100 = 4/100 = 1/25 = 0.04.
You can also just move the decimal two place values to the left to divide by 100. For example, 4/100 = 4. /100 = 0.04 = 1/25

18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does 
per minute (if we multiply this by 30 we have the completed job)
-Sophie does 
of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:
They will do 
of the job per minute.

, we can put this in one equation like this:
where x is the total times we need to do of the job to complete it. We solve for x:
