Question

pls tell answer pleasssssssssssssssssssssss​

Answer 1

Answer:

3/8

Step-by-step explanation:

Let the numerator be x.

Denominator = x+5

According to Question,

(x+2) / (x+5+2) = 1/2

=> (x+2) / (x+7) = 1/2

=> 2(x+2) = 1(x+7)

=> 2x+4 = x+7

=> 2x-x = 7-4

=> x = 3

Hence, numerator = 3

Denominator = 3+5 = 8

Therefore, the rational number is 3/8.

☆ Numerator = x

☆ Denominator = x + 5

$\color{aqua}{\star \large\underline{{\boxed{\sf\blue{Solution:-}}}}}$

According to the question:-

$\sf \mapsto \: \frac{ \times + 2}{x + 5 + 2} = \frac{1}{2}$

$\sf \mapsto \frac{ x + 2}{x + 7} = \frac{1}{2}$

$\sf \mapsto \: 2 (x + 2) = 1( x + 7)$

$\sf \mapsto 2x + 4 = x + 7$

$\sf \mapsto 2x - x = 7 - 4$

$\sf \mapsto x = 3$

Therefore ,

$\sf \red \star \: Numerator \: of \: rational \: number = 3$

$\sf \red\star \: Denominator \: of \: rational \: number = 3 + 5 = 8$

Hence ,

$\sf \: The \: rational \: number = \large{\frac{3}{8} }$
