Answer 1

a) 3/8 : 2/3 = 3/8 * 3/2 = 9/16
b) 5/8 : 15/32 = 5/8 * 32/15 = 4/3 = 1 i 1/3
c) 12/31 : 1 4/11 = 12/31 : 15/11 = 12/31 * 11/15 = 44/155
d) 3 1/2 : 5/9 = 7/2 : 5/9 = 7/2 * 9/5 = 63/10 = 6 i 3/10
e) 4 1/5 : 7/15 = 21/5 * 15/7 = 9
f) 8 2/3 : 5/13 = 26/3 * 13/5 = 338/15 = 22 i 8/15
g) 2 7/10 : 4 1/20 = 27/10 : 81/20 = 27/10 * 20/81 = 2/3
h) 4 5/6 : 1 1/5 = 29/6 : 6/5 = 29/6 * 5/6 = 145/36 = 4 i 11/36
i) 3 3/7 : 1 1/20 = 24/7 : 21/20 = 24/7 * 20/21 = 160/49 = 3 i 13/49
j) 1/2 : 1/3 = 1/2 * 3/1 = 3/2 = 1 i 1/2
k) 4/5 : 2/3 = 4/5 * 3/2 = 6/5 = 1 i 1/5
l) 5/7 : 3/7 = 5/7 * 7/3 = 5/3 = 1 i 2/3
m) 15/16 : 9/20 = 15/16 * 20/9 = 25/12 = 2 i 1/12
n) 4/15 : 8 = 4/15 * 1/8 = 1/30
o) 60 : 4 4/5 = 60 : 24/5 = 1/60 * 5/24 = 1/288
