There are two methods that can be used to write 0.368 in expanded form.
Method-1:
Take the first number after the decimal point and divide it by 10. Take the second number after the decimal point and divide it by 100. Take the third number after the decimal point and divide it by 1000. Lastly, add all of them.

Method-2:
Multiply first number after decimal point with 0.1; multiply second number after decimal point with 0.01; multiply third number after decimal point with 0.001, and add them all.
(3 * 0.1) + (6 * 0.01) + (8 * 0.001) = 0.368
 
        
        
        
Isn't the ticket the entrance fee? 
oh well, 
assuming that
each person paid 0.50 to enter
if a certain gropu paid 28 to enter, how many peple
total cost=costperperson times numbe rof person
28=0.5 times number of persons
divide by 0.5 or multiply both sides by 2 (same thing)
56=number of person
