URGENT!!!

Answer 1

a) 1.(12/25 / 4/5)= 3/5 / 9/35= 7/3
b) 1.(4/5 / 9/35)=28/9 / 12/25= 175/27 
c) 1. (25/36 / 7/16)= 100/63       2. 60/49 / 162/ 7= 10/189   3. 100/63 / 10/189 = 30
d) 1. (11/12 / 13/18) = 33/26        2. 33/26 / 22/33= 99/52 
e) 1. (19/45 / 7/30) =38/21         2. 38/21 / 19/21  = 2
f)  1. (13/12 / 7/15) =65/28          2/ 65/28 / 39/70 = 25/6
