Question 1
Represent these numbers on the number line.
 7/4
 5/6
Answer
Question 2
Represent on the number line.
Answer:
Question 3
Write five rational numbers which are smaller than 2.
Answer:
2 can be written as $\frac {14}{7}$
So the five rational number smaller than
$\frac {8}{7}, \frac {9}{7},\frac {10}{7},\frac {11}{7},\frac {12}{7}$
Question 4
Find ten rational numbers between $\frac {2}{5}$ and $\frac {1}{2}$
Answer:
Creating same denominator of both the numbers
$\frac {2}{5} =  \frac {8}{20}$
$\frac {1}{2}= \frac {10}{20}$
So ten rational numbers will be
$\frac {7}{20},\frac {6}{20}, \frac {5}{20} , \frac {4}{20} ,\frac {3}{20}, \frac {2}{20}, \frac {1}{20}, 0 ,\frac {1}{20},\frac {2}{20}$
Question 5
Find five rational numbers between
(i) $ \frac {2}{3}$ and $\frac {4}{5}$
(ii) $ \frac {3}{2}$ and $\frac {5}{3}$
(iii) $\frac {1}{4}$ and $\frac {1}{2}$
Answer:
 Creating same denominator
$ \frac {2}{3} = \frac {30}{45}$
$\frac {4}{5}= \frac {36}{45}$
So five rational number will be
$ \frac {31}{45}, \frac {32}{45}, \frac {33}{46}, \frac {34}{45},\frac {35}{45}$
 Creating same denominator
$ \frac {3}{2}=  \frac {9}{6}$
$\frac {5}{3}= \frac {10}{6}$
So five rational number will be
$\frac {8}{6}, \frac {7}{6},1, \frac {5}{6}, \frac {4}{6}$

Creating same denominator
$\frac {1}{4}= \frac {8}{32}$
$\frac {1}{2}= \frac {16}{32}$
So five rational number will be
$\frac {10}{32}, \frac {11}{32}, \frac {12}{32},\frac {13}{32}, \frac {14}{32}$
Question 6
Write five rational numbers greater than  2.
Answer:
2 can be written as 14/7
So the five rational number smaller than
8/7,9/7,10/7,11/7,12/7
Question 7
Find ten rational numbers between $\frac {3}{5}$ and $\frac {3}{4}$
Answer:
$ \frac {3}{5}= \frac {48}{80}$
$\frac {3}{4}=\frac {60}{80}$
So ten rational numbers are
49/80, 50/80, 51/80, 52/80, 53/80, 54/80, 55/80, 56/80, 57/80, 58/80
