Shobha spent $\frac{1}{3}$ times of 10 hours watching television.
$\Rightarrow \frac{1}{3}\times 10=\frac{10}{3}or3\frac{1}{3}$
$\therefore$ Shobha spent $\frac{10}{3}$ hours or  $3\frac{1}{3}$ hours (which is 3 hours 20 minutes)  watching  television.

There are 24 hours in a day.
$\Rightarrow$ 6 hours of a day
$=\frac{6}{24}$ 
$=\frac{1}{4}$ (expressed in the simplest form) 
$\Rightarrow \frac{6}{24}$ and $\frac{1}{4}$ are equivalent fractions.
$\therefore$ 6 hours of a day represents $\frac{1}{4}th$ of a day.

$\frac{2}{1}\times \frac{1}{2}=1$
$\frac{3}{1}\times \frac{1}{4}=\frac{3}{4}$
$\frac{7}{1}\times \frac{1}{3}=\frac{7}{3}=2\frac{1}{3}$
$\frac{17}{1}\times \frac{1}{5}=\frac{17}{5}=3\frac{2}{5}$

$\frac{6}{3}=2=\frac{2}{1}$
$\therefore$ LCM for the fractions $\frac{1}{2},\frac{3}{4},\frac{4}{5},\frac{3}{2},\frac{2}{1}$ is 20
$\Rightarrow$$\frac{1}{2}=\frac{10}{20}$
$\Rightarrow$$\frac{3}{4}=\frac{15}{20}$
$\Rightarrow$$\frac{4}{5}=\frac{16}{20}$
$\Rightarrow$$\frac{3}{2}=\frac{30}{20}$
$\Rightarrow$$\frac{2}{1}=\frac{40}{20}$
Now that the denominator is equal, we can compare the fractions. The numerator 40 is the greatest and 10 is the least. Hence, the corresponding original fractions will be the greatest and the least.
$\therefore$ Greatest fraction = $\frac{6}{3}$ = 2
Smallest fraction = $\frac{1}{2}$ = 0.5

(a) Total no of balloons = 55
Balloons left with Nisha = 55 - 46 = 9
Fraction of balloon left = $\frac{9}{55}$
Balloons left with Nisha = 46 - 6 = 40
Fraction of balloon left with Nisha = $\frac{40}{46}=\frac{20}{23}$
(b)The total weight of the fruits = $3\frac{1}{2}+4\frac{3}{4}$
= $\frac{7}{2}+\frac{19}{4}$
=  $\frac{14}{4}+\frac{19}{4}$
=  $\frac{33}{4}$
=  $8\frac{1}{4}$
(c) $2\frac{2}{3}+3\frac{1}{2}=\frac{8}{3}+\frac{7}{2}$
                         $=\frac{8\times 2+7\times 3}{6}$
                        $=\frac{16+21}{6}$
                        $=\frac{37}{6}$
                       $=6\frac{1}{6}$

There are total of 11 numbers from 0 to 10
1) Number of odd numbers (1,3,5,7,9) = 5. 
$\therefore$ Fraction of odd numbers = $\frac{5}{11}$
2) Number of prime numbers (2,3,5,7) = 4
$\therefore$ Fraction of prime numbers $\frac{4}{11}$
3) Number of even numbers (2,4,6,8,10) = 5
$\therefore$ Fraction of even numbers $\frac{5}{11}$

(b) Length of rope = 9.85m
After dividing the rope into 5 equal parts each part will be $\frac{1}{5}th$ of the total part.
$\Rightarrow \frac{1}{5}\times 9.85=\frac{9.85}{5}=1.97m$

(a) No of parts Arush has eaten = 4
Total no of parts = 6
So fraction of parts he has eaten = $\frac{4}{6}=\frac{2}{3}$
Fraction of watermelon remaining = $1-\frac{2}{3}=\frac{3-2}{3}=\frac{1}{3}$
The fractions $\frac{2}{3}$ and $\frac{1}{3}$ are called proper fractions.
(b) Total time of Suman’s study =  $5\frac{2}{3}=\frac{17}{3}$ hours
Time devoted by her for Science and Mathematics =  $2\frac{4}{5}=\frac{14}{5}$ hours
Thus, time devoted by her for other subjects = $\frac{17}{3}-\frac{14}{5}$
= $\frac{17\times 5}{15}-\frac{14\times 3}{15}$
= $\frac{43}{15}$
= $2\frac{13}{15}$
