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 number of kids who have both dogs and cats can be calculated by adding the number of kids with dogs (20) to the number of kids with cats (15), then subtracting the total number of kids (29) from that sum. Therefore, 6 kids have both dogs and cats.
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
