Changing Numbers To Prescribed Values Under Special Limitations
Posted: Feb 9, 2013 8:29 AM

x=1825+91/1217
y=7+2/3
z=1827+2/3

Is there any way to turn x into z only using the first two terms, andor a constant, and the operators '+','-','*','/'.

I know I can take ((x)-(x mod 10)) + y = z, but this uses a modulus.

... Basically the core of the question is can I change any number's last digit and its decimal value to something I decide by only using the number itself and the desired digit and decimal?

... I feel like splitting the numerator and denominator and running independent operations on each might be the way to go.
