okay. Say x=0.767676...
now, lets multiply 100 with x to get 100x=76.767676...
now, let's subtract x from 100x, thus the right of decimal point will disappear, leaving us with
99x=76 so if you divide both sides of the equal sign by 99, then we get x= 76/99. Since x also equals 0.767676... then x=76/99=0.767676..
