l) 2,(2) :2,2*2,2(2) = 200/90 :22/10 * 200/90 = 200/90 : 198/90 * 200/90 = 200/90*90/198*20/9= 200/1*90/198*20/9=100/1*1/99*20/9 = 2000/891 = 2,24467

m)
1,(5)+1,5-1,5(1):1,1(5) = 14/9+ 15/10 - 136/90 : 104/90 = 140/90 + 150/90 -136/90: 104/90 = 290/90 -136/90 : 104/90 = 154/90 :104/90 = 154/90 * 90/104 = 77/1 *1/52 = 77/52
