Question

What should be added to 108/10
get42/5​

Answer 1

Answer:

$\mathbb\blue{LET:-}$

Let the number be x

$\mathbb\blue{SOLUTION:-}$

$\mathtt{ \frac{108}{10} + x = \frac{42}{5} }$

$\mathtt{ \frac{108 + 10x}{10} = \frac{42}{5} }$

$\mathtt{108 + 10x = \frac{42}{5} \times 10 }$

$\mathtt{108 + 10x = 42 \times 2}$

$\mathtt{108 + 10x = 84}$

$\mathtt{ 10x = 84 - 108}$

$\mathtt{ 10x = - 24}$

$\mathtt{x = \frac{ - 24}{ 10} }$

$\mathtt{x = \frac{ - 12}{5} }$

$\mathbb\blue{VERIFICATION:-}$

$\mathtt{ \frac{108}{10} + \frac{( - 12)}{5} = \frac{42}{5} }$

$\mathtt{ \frac{108 - 24}{10} = \frac{42}{5} }$

$\mathtt{ \frac{84}{10} = \frac{42}{5} }$

$\mathtt{ \frac{42}{5} = \frac{42}{5} }$

$\mathtt\blue{LHS = RHS}$

$\mathtt\blue{HENCE,VERIFIED}$
