Answer 2

Answer:

$Value \: of \: x = \frac{15}{2}$

Step-by-step explanation:

$Given \: four \: numbers \: \frac{1}{2}, \frac{1}{3},\\\frac{1}{5}\: and \: \frac{1}{x} \: are \: proportional$

$If \: a,b,c \:and \: d\: are \: proportional\: then\\a\times d = b \times c$

$\implies \frac{1}{2}\times \frac{1}{x} = \frac{1}{3}\times \frac{1}{5}$

$\implies \frac{1}{2x}= \frac{ 1}{15}$

$\implies 2x = 15$

$\implies x = \frac{15}{2}$

Therefore,

$Value \: of \: x = \frac{15}{2}$
