Given:
$(i)$. $-\frac{5}{7}\square\ \frac{2}{3}$
$(ii)$. $-\frac{4}{5}\square\ -\frac{5}{7}$
$(iii)$. $-\frac{7}{8}\square\ \frac{14}{-16}$
$(iv)$. $-\frac{8}{5}\square\ -\frac{7}{4}$
$(v)$. $\frac{1}{-3}\square\ \frac{-1}{4}$
$(vi)$. $\frac{5}{-11}\ \square\ \frac{-5}{11}$
$(vii)$. $0\ \square\ \frac{-7}{6}$
To do: To fill in the boxes with the correct symbol out of >, <, and =.
Solution:
$(i)$. $-\frac{5}{7}\square \frac{2}{3}$
Here LCM of $7$ and $3$ is $21$.
So, $-\frac{5}{7}=-\frac{5\times 3}{7\times 3}$
$=-\frac{15}{21}$
And $\frac{2}{3}=\frac{(2\times 7)}{(3\times 7)}$
$=\frac{14}{21}$
On comparing both fractions:
$-\frac{15}{21}$ < $\frac{14}{21}$
Therefore, $-\frac{5}{7}$ < $\frac{2}{3}$
$(ii)$. $\frac{-4}{5}\square -\frac{5}{7}$
Here LCM of $5$ and $7$ is $35$
$-\frac{4}{5}=\frac{(-4\times 7)}{(5\times 7)}$
$=-\frac{28}{35}$
And $-\frac{5}{7}=\frac{(-5\times 5)}{(7\times 5)}$
$=-\frac{25}{35}$
Here, $-\frac{28}{35}$ <$-\frac{25}{35}$
Therefore, $\frac{-4}{5}$ < $-\frac{5}{7}$
$(iii)$. $\frac{-7}{8}\square \frac{14}{-16}$
Here LCM of $8$ and $16$ is $16$.
So, $-\frac{7}{8}=\frac{(-7\times 2)}{(8\times 2)}$
$=-\frac{14}{16}$
And $\frac{14}{-16}=-\frac{14\times 1}{16\times 1}=-\frac{14}{16}$
On comparing, $-\frac{14}{16}$=-$\frac{14}{16}$
Therefore, $\frac{-7}{8}=\frac{14}{-16}$
$(iv).$ $-\frac{8}{5}\square -\frac{7}{4}$
Here LCM of $5$ and $4$ is $20$.
So, $-\frac{8}{5}=\frac{(-8\times 4)}{(5\times 4)}$
$=-\frac{32}{20}$
And $-\frac{7}{4}=\frac{(-7\times 5)}{(4\times 5)}$
$=-\frac{35}{20}$
Or $-\frac{32}{20}$ > $-\frac{35}{20}$
On comparing both rational numbers we have : $-\frac{8}{5}$ > $-\frac{7}{4}$
$(v)$. $\frac{1}{-3}\square -\frac{1}{4}$
Here LCM of $3$ and $4$ is $12$.
So, $\frac{1}{-3}=\frac{(1\times 4)}{(-3\times 4)}$
$=-\frac{4}{12}$
And $-\frac{1}{4}=\frac{(-1\times 3)}{(4\times 3)}$
$=-\frac{3}{12}$
$-\frac{4}{12}$ < $-\frac{3}{12}$
On comparing both rational numbers we have: $\frac{1}{-3}$ < $-\frac{1}{4}$
$(vi)$. $\frac{5}{-11}\square -\frac{5}{11}$
On comparing both given rational numbers we have:
$-\frac{5}{11}$= $-\frac{5}{11}$
$(vii)$. $0\square \frac{-7}{6}$
Here, since all the negative numbers are less than zero, hence,
$0$ > $\frac{-7}{6}$
