4 5/12- 3 7/18 =5312 - 61/18 = ( 159-122) / 36 37/36
37/36 9 25/100 37/36 * 100/925 = 3700 /33300 37/333
37/333 5/6 = (74 + 555 ) / 666= 629/666
4/10 + 1/8 = ( 20 +5 ) / 40= 25/40 = 5/8
5/8+75/100 = ( 250 +300) / 400 = 550/440 = 55/40 * 2/3 = 110/120
629/666 / 110/120 = 629/666 *120/110 = 8280/73260 = 828/7326 = 138/1221
