D=1:0.6
As you can see, 18 is a constantly repeating number in this situation. So take out the 2.3 to get 0.01818..... To make infinitely long rational numbers with repeating digits into a fraction, put it over 99. so 0.1818...... would be 18/99. But since it is 0.0181818...., you have to put 18 over 990. 18/990 is 2/110, which is 1/55. Now you have to add 2.3 to 1/55 which will be 2 7/22
