Question

please answer it correctly. this question is from 8th class so please solve this sum in correct manner. so we can understand it​

Answer 1

Required Answer :

Now, Multiplicative inverse of

$\tt \: \dfrac{ - 5}{ \: \: \: 7} = \dfrac{ \: \: \: 7}{ - 5}$

So, Now let's find the product :

${ : \implies} \sf \: \frac{3}{4} \times \frac{7}{ - 5} \\ \\ \\ { : \implies} \sf \frac{ \: \: 21}{ - 20}$

• Hope this helps!!

Answer 2

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

Multiplicative inverse of $\sf\dfrac{ - 5}{7} = \dfrac{ - 7}{5}$

Now , product

$\longmapsto \sf \frac{3}{4}\times \frac{( - 7)}{5}$

$\longmapsto \sf \frac{ - 21}{20}$
