4.5+ 3 2/3 = 4 3/6 + 3 4/6 = 7 7/6 = 8 1/6
3,2 - 1 3/5 = 3.2-1.6=1.6
3/7*4.9 = 3/7 * 49/10= 2.1
4,8:2 2/5= 24/5 * 5/12 = 2
6 1/2 + 2.75 = 9,25
7.8 - 5 5/6 = 7 24/30 - 5 25/30 = 1 29/30
3 1/9:1.4 = 28/9 * 10/14= 2 2/9
2 4/5 + 5.4 = 2.8+5.4=8.2
2 3/7 - 1.4 = 2 3/7 - 1 4/10 = 2 30/70 - 1 28/70 = 1 2/70 = 1 1/35
2.4*2 1/3 = 24/10 * 7/3 = 5.6
4.8 : 6/7 = 48/10 * 7/6 = 5.6
