I'm not sure if I used the estimation symbol correctly, correct it if it's wrong please. Otherwise, this should be it, as 3 is a factor of 54, the division will be easier.

why does 5450 round off to 5400 tho? and not 5500?
Thanks!
In response to your 1st comment, 5400 is easily divisible by 3, but not 5500
