Answer 2

a) x:0,6=3,(3)
3,(3)=(33-3)/9=30/9=10/3
0,6=6/10=3/5
x:3/5=10/3
x=10/3 ×3/5=2


x:2,5=0,2(6)
2,5=25/10=5/2
0,2(6)=(26-2)/90=24/90=4/15
x:5/2=4/15
x=4/15×5/2
x=2/3

0,4:x=1,(3)
0,4=4/10=2/5
1,(3)=(13-1)/9=12/9=4/3
2/5:x=4/3
x=2/5:4/3=2/5×3/4=3/10

3,5:x=0,3(8)
3,5=35/10=7/2
0,3(8)=(38-3)/90=35/90=7/18
7/2 :x =7/18
x=7/2:7/18=7/2×18/7=9
