example:
12X+8=6X+11
-6X -6X
6X+8=11
-8 -8
6X=3
now divide by 6
X=1/3

I believe you're asking to solve for x if x/2.30 = 0.69. If so, x = 1.59.
the fraction is percent over 100 and fraction over the whole. Whatever number is missing you multiply across in an X with the end being the empty space.
Call your number "x", and calculate 10 times that number.10x = 7.777...x = 0.777...Subtract the second equation from the first, and you get:9x = 7If you solve this for "x", you get the number as a fraction. In this case, it is 7/9.
You cannot solve a fraction. You can solve a question about fractions, you can carry out basic operations with fractions, convert them from one form to another but none of these is "solving" them.
If x = 0.16666, then 10x = 1.6666 and 100x = 16.6666 Subtract the second one from the third one. 90x = 15 Solve for x x = 15/90 Reduce x = 1/6 1/6 = 0.16666
