​

Answer 1

SOLUTION :

$\longrightarrow\sf \dfrac{-5}{12}$

$\longrightarrow\sf \dfrac {-3}{4}$

• First make their denominator equal. by taking LCM.

• We know LCM of 12 and 4 is 12.

• $\longrightarrow\sf \dfrac {-5}{12}$

$\longrightarrow\sf {\dfrac {-5\times1}{12\times 1}}$

$\longrightarrow\sf {\dfrac {-5}{12}}$

• $\longrightarrow\sf \dfrac {-3}{4}$

$\longrightarrow\sf {\dfrac {-3\times3}{4\times 3}}$

$\longrightarrow\sf \dfrac {-9}{12}$

Here

$\longrightarrow\tt\dfrac {-5}{12}\lt\dfrac {-9}{12}$

$\longrightarrow{\boxed{\bf \dfrac {-5}{12}\lt \dfrac {-3}{4}}}$
