Consider the numbers in the fraction: 
6 is 2 times 3 
The denominator 15 is 5 times 3 
Numerator : Denominator = 6 : 15 or 2 : 5 
If the Denominator is to be 20 it is 4 times 5, 
the Numerator has to be 4 times 2 
Answer: 
6/15 = 8/20

You get 1.3333
Now multiply 6 by 1.3333333
You get 8.
6/15=8/20
