Answer:
Alright, so we have to find the LCM of 2.75 and 3.5.
A good start would be to multiply them together to get 9.625, but we want a whole day!
This would be every 77 days :)
When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.
To work it out:
(20200 + 14500 + 18800 + 9300 + 2200) divide by the number of regions, in this case 5.
The answer is 13000 which is A
Basically the mean is adding all the numbers divided by the amount of numbers you added. So in this case adding the data of the 5 regions divided by 5.
Hope to have helped :)
