The hcf of 15 and 20 is 5
Both 15 and 20 can go into 60, as they are both factors of that number.
The only common factor of 15, 20 and 24 is 1.
15/5=3 100/5=20
The GCF of 15 and 20 is 5
3/20=.15 .15*100=15%

55 goes into 20, 4 times.5 goes into 75, 15 times.
25
The number is 15.
The GCF of 15 and 20 is 5
1, 2, 4, 5, 10, 20.
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.
The answer is 20. 4 into 20 goes five times and 20 into 20 goes once, of course; so the lowest number that they can both be multiplied into is 20. Try looking at this for help when you need it.http://www.helpwithfractions.com/least-common-multiple.html
15/20 = 3/4 Divide both 15 and 20 by 5.
