Answer 2

a) 3/8 : 2/3 = 9/24 : 16/24 = 9/24 x 24/16 = 9/1 x 1/16 = 9/16

b) 8 : 15/32 = 8/1 : 15/32 = 1/1 : 15/4 = 1/1 x 4/15 = 4/15

d) 3 1/2 : 5/9 = 7/2 : 5/9 = 63/18 : 10/18 = 63/18 x 18/10 = 63/1 x 1/10 = 63/10 = 6 3/10

e) 4 1/5 : 7/15 = 21/5 : 7/15 = 63/15 : 7/15 = 63/15 x 15/7 = 9/1 x 1/1 = 9/1 = 9

f) 8 2/3 : 5/13 = 26/3 : 5/13 = 2/3 : 5/1 = 2/3 x 1/5 = 2/15

g) 2 7/10 : 4 1/2 = 27/10 : 9/2 = 27/10 x 2/9 = 3/1 x 1/1 = 3/1 = 3

h) 4 5/6 : 1 1/5 = 29/6 : 6/5 = 29/1 : 1/5 = 29/1 x 5/1 = 145/1 = 145

i) 3 3/7 : 1 1/20 = 24/7 : 21/20 = 6/1 : 3/5 = 6/1 x 5/3 = 2/1 x 5/1 = 10/1 = 10

j) 1/2/1/3 = 1/2 : 1/3 = 3/6 : 2/6 = 3/6 x 6/2 = 3/1 x 1/2 = 3/2 = 1 1/2

k) 4/5/2/3= 4/5 : 2/3 = 12/15 : 10/15 = 12/15 x 15/10 = 6/1 x 1/5 = 6/5 = 1 1/5

l) 5/7/3/7= 5/7 : 3/7 = 5/7 x 7/3 = 5/1 x 1/3 = 5/3 = 1 2/3

m) 15/16/9/20= 15/16 : 9/20 = 15/16 x 20/9 = 15/4 x 5/9 = 75/36 = 2 3/36 = 2 1/12

n) 4/15/8= 4/15 : 8 = 4/15 : 8/1 = 4/15 x 1/8 = 1/15 x 1/2 = 1/30

 

Niestety nie udało mi sie zrobić zadań c) i o) bo nie wiedzialem czy zapomniałaś jakiegoś znaku czy coś.
