8 and 4 2 and 15
120
I think 8
The number is 120.
120
8 is 15% of what number
The smallest number that 8 or 12 or 20 will all go in to is 120 120 = 20 x 6 = 12 x 10 = 8 x 15 as there is then no number that goes into 6 and 10 and 15 equally.
LCM(8, 5, 15) = 120 so the answer is 120 and all its multiples.
15 can of course go into 125, but not an even number of times. 125 / 15 = 8-1/3
15
I believe that 120 is the LCM. All you have to do is list the multiples of 15 until you get a number that is divisible by 8.
they all go into 120
