If 5 key chains cost 11.5 then one key chain costs 11.5 divided by 5, which is 2.3 so 15 key chains cost 2.3 x 15, which is 34.5
Actually the cost of 5 chains is 11.25 not 11.50.
so divide 11.25 by 5 to find the cost of one chain = 2.25
now multiply 2.25 by 15 to find the cost of 15 chains = 33.75
Another way to do it is to see that 15 chains is 3 times more than 5 so multiply the cost of 5 chains by 3
5x3 = 33.75

11.25 is 75 percent of what number?
To get this, do this: Multiply 11.25 by 100, then divide that by 75. 11.25•100=1125 1125/75=15 15 is your answer. Now if you had 15 and not 11.25 you do this: 15•.75 which is then 11.25
