Answer 1

a) 5/7 : a = 10 
    a = 5/7 : 10  = 5/70 

b) = > a = 3/11 x 1/15 = 3/165 

c) = > a = 17*1/2 : 3*1/2 = 35/2 x 2/7 = 35/7 = 5 

d) = > a = 4*1/11 : 1*4/11  = 45/11 x 11/15 = 3 

e) = > a = 5*1/7 x 14 = 36/7 x 14 = 72 

f) = > a = 226 /125 : 339/125 = 226/125 x 125/339 = 226/339 

Answer 2

a) 5/7 : x = 10
    x = 5/7 : 10 = 5/7 x 1/10 = 5/70
b) x : 1/15 = 3/11
   x = 1/15 x 3/11 = 3/165
c) 17 si 1/2 : x = 3 si 1/2
   35/2 : x = 7/2
   x = 35/2 : 7/2 = 35/2 x 2/7 = 35/7 = 5
d) 4 si 1/11 : x = 1 si 4/11
    45/11 : x = 15/11
    x = 45/11 : 15/11 = 45/11 x 11/15 = 45/15 = 3
e) x : 14 = 5 si 1/7
    x : 14 = 36/7
    x = 36/7 x 14 = 36 x 2 = 72
f) 226/125 : x = 339/125
   x = 226/125 : 339/125 = 226/125 x 125/339 = 226/339 = 2/3
