Compare the fractions and put an appropriate sign.
(a) $ \frac{3}{6} \square \frac{5}{6} $
(b) $ \frac{1}{7} \square \frac{1}{4} $
(c) $ \frac{4}{5} \square \frac{5}{5} $
(d) $ \frac{3}{5} \square \frac{3}{7} $
To do:
We have to compare the given fractions and put appropriate signs.
Solution:
To compare we need to convert the given fractions into fractions with equal denominators.
(a) Here,
$\frac{3}{6}$ and $\frac{5}{6}$ have equal denominators.
$3<5$
Therefore,
$\frac{3}{6} < \frac{5}{6}$
(b)
LCM of denominators 7 and 4 is 28.
Multiply $\frac{1}{7}$ by $\frac{4}{4}$
This implies,
$\frac{1}{7}\times\frac{4}{4}=\frac{4}{28}$
Multiply $\frac{1}{4}$ by $\frac{7}{7}$
$\frac{1}{4}\times\frac{7}{7}=\frac{7}{28}$
$4<7$
Therefore,
$\frac{4}{28} < \frac{7}{28}$
This implies,
$\frac{1}{7} < \frac{1}{4}$(c) Here,
$\frac{4}{5}$ and $\frac{5}{5}$ have equal denominators.
$4<5$
Therefore,
$\frac{4}{5} < \frac{5}{5}$
(d) LCM of denominators 5 and 7 is 35.
Multiply $\frac{3}{5}$ by $\frac{7}{7}$
This implies,
$\frac{3}{5}\times\frac{7}{7}=\frac{21}{35}$
Multiply $\frac{3}{7}$ by $\frac{5}{5}$
$\frac{3}{7}\times\frac{5}{5}=\frac{15}{35}$
$15<21$
Therefore,
$\frac{15}{35} < \frac{21}{35}$
This implies,
$\frac{3}{7} < \frac{3}{5}$
