Answer:
- 27 is 18 multiplied by 3/2
- 18 is 2/3 of 27
Step-by-step explanation:
The ratio of the two numbers is 18/27 = (2·9)/(3·9) = 2/3.
So, if you're starting with 27 and you want to scale it down to 18, you multiply by the scale factor 2/3.
If you're starting with 18 and you want to scale it up to 27, you use the inverse of the above scale factor. That inverse is 3/2.

There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.
In his journey, she walks for 15 minutes and a train journey for about 53 minutes.
Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.
Therefore, the average waiting time, in minutes, at each of the three train stations will be 
minutes. (Answer)
