Canceling, we have C X = 100 10 \frac {C}{X} = \frac {100}{10} , in Roman Numerals. So 10 \boxed {10} .

Cancel the D, B and Es we get C X = 10 \frac{C}{X} = \boxed{10} , if we interpret them as roman numerals. :)

Wait a moment @Zi Song Yeoh , Were you a ROMAN GENERAL in your previous birth???? But your problems are really innovative......

I thought of C X \frac{C}{X} but not Roman Numerals
