a) 
$\frac {5}{10}$ 
There are 5 tenths in the number 
.5 
b) 
$3 + \frac {7}{10}$ 
There are 3 ones and 7 tenths 3+.7 
3.7 
c) 
$200 + 60 +5 + \frac {1}{10}$ 
There are 2 hundred ,6 tens,5 ones and 1 tenth 200+60+5+.1 
265.1 
d) 
$70+ \frac {8}{10}$ 
There are 7 tens, 0 ones and 8 tenths in the number 
70.8 
e) 
$ \frac {88}{10}$ 
Here the numerator is bigger than denominator, so converting into mixed fraction we get 8 + 8/10 
8.8 
f) 
$ 4 \frac {2}{10}$ 
4 + 2/10 
4.2 
g) 
$ \frac {3}{2}$ 
For writing in decimal notation, the denominator of the fraction should be 10. So, we make an equivalent fraction as, 3/2 = 15/10 Here the numerator is bigger than denominator, so converting into mixed fraction we get 1 + 5/10 
1.5 
h) 
$ \frac {2}{5}$ 
For writing in decimal notation, the denominator of the fraction should be 10. So, we make an equivalent fraction as, 2/5 = 4/10 
.4 
i) 
$ \frac {12}{5}$ 
For writing in decimal notation, the denominator of the fraction should be 10. So, we make an equivalent fraction as, 12/5 = 24/10 Here the numerator is bigger than denominator, so converting into mixed fraction we get 2 + 4/10

a) 
A 
A represents the 8^{th} equal part between 0 and 1. So, A is 0.8. 
b) 
B 
B represents the 3^{rd} equal part between 1 and 2. So, B is 1.3 
c) 
C 
C represents the 2^{nd} equal part between 2 and 3 and hence is the number 2.2 
d) 
D 
D is 2.9, the 9^{th} equal part between 2 and 3.
