Answer 1

b) 1 1/3 * 2,7 = 4/3 * 27/10 = 108/30 = 3 18/30 = 3 6/10 = 3 3/5
c) 1 1/3 * 3 3/4 * 0,2 = 4/3 * 15/4 * 1/5 = 60/12 * 1/5 = 60/60 = 1
d)  3/4 : 0,0375 = 3/4 : 375/10000 = 3/4 * 10000/375 = 30000/1500 = 20
e) 0,48 : 1 1/7 = 48/100 : 8/7 = 48/100 * 7/8 = 336/800 = 169/400
f) 3 i 7/9  / 1,7 :2 = 34/9 / 17/10 * 1/2 = 34/9 : 17/20 = 34/9 * 20/17 = 2/9 * 20 = 40/9 = 4 4/9
