5) 2/5 [ same working out as above]
6) 3 & 7/10
7) 4 & 1/4
8) 2 & 3/20
9) 0.3
10) 0.5
11) 0.6
12) 0.66
13) 6.4
14) 12.06
15) 7.22
16) 1.15
17) 3/4
18) 1 & 1/2
19) 1 &1/4, 1.25
20) A because the number 0.125 is less than 1/4, thus point A is the only possible options (additionally point a represents 1/8 which is equivalent to 0.125)
