To round off to 10, the difference should range from 5 to 14. If the difference between two numbers is from 5 to 14, they all are rounded to 10.
Example:
(near to 10)
![26-15=11](https://tex.z-dn.net/?f=26-15%3D11)
![46-39=7](https://tex.z-dn.net/?f=46-39%3D7)
![50-42=8](https://tex.z-dn.net/?f=50-42%3D8)
6:15 is in ratio form..... If you mean fraction form, a ratio is equivalent to a fraction, so the answer is 6/15
