The factors of 8 are: 1, 2, 4, and 8.The factors of 20 are: 1, 2, 4, 5, 10, and 20.The factors common to 8 and 20 are: 1, 2, and 4.Each of these guzinta both 8 and 20.
Both 15 and 20 can go into 60, as they are both factors of that number.

6x + 8 = 20 Subtract 8 from both sides: 6x = 12 Divide both sides by 6: x = 2
40% x * 20 = 8 divide both sides by 20 end up with .4 as your answer. multiply * 100 = 40 %

160/8 = 20
The LCM of 8 & 20 is... 40
They both go into 1440, for example.

80/x = 8/20 Taking reciprocals of both sides, x/80 = 20/8 Multipling both sides by 80, x = 80*20/8 simplifying: x = 20*80/8 = 20*10 = 200.
6x + 8 = 20 Subtract 8 from both sides: 6x = 12 Divide both sides by 6: x = 2
40% x * 20 = 8 divide both sides by 20 end up with .4 as your answer. multiply * 100 = 40 %
They both go into multiples of 60 such as 480.
First of all you need to line them up. 8/20 - 2/5 Next you need to find a common denominator. 20 is a common denominator between the 2. Then you change both denominators to the common one. 8/20=8/20, 2/5 x 4/4= 8/20 {Since 5x4=20, you have to do that on both sides to get the common denominator.} Then you subtract 8/20 - 8/20 = 0. So the answer is 0
As 8 is even, and 3 is odd, I think only 1 can go into both.
