It is 20 - (-4) = 20 + 4 = 24
The difference between 5 and 20 is 15.

the even numbers between 10 and 20 are :10,12,14,16,18,20 so there are 4 even numbers between 10 and 20 (without counting the 10 and 20 =)) i hope this helped u =)
Since 4 is a factor of 20, it is automatically the GCF.
3-4 = -1 -21 the distance between -1 and -21 is -20 -20 -1 = -21
To be a multiple of 4, 10 and 20 the number must be a multiple of their lowest common multiple. lcm(4, 10, 20) = 20 What is required is a multiple of 20 between 61 and 107. The numbers 80 and 100 both satisfy the problem of being between 61 and 107 and being a multiple of 4, 10 and 20.
The hcf is 4
Example 2/4 + 4/5 convert that to 2/4 = 10/20 4/5 = 16/20 10/20 + 16/20 = 26/ 20, reduce that to 13/10
Factors of 20 are: 1 2 4 5 10 and 20
17 = 2 + 3 + 5 + 7
