Question

what is the value of of x if 2,7,5 (x÷2) are in proportion?

Answer 1

$\text{2, 7, 5 and \frac{x}{2} are in proportion}\\ \\ \Rightarrow 2:7 :: 5 : \frac{x}{2} \\ \\ \Rightarrow \frac{2}{7} = \frac{5}{ \frac{x}{2} } \\ \\ \Rightarrow \frac{2}{7} = \frac{10}{x} \\ \\ \Rightarrow x = 10 \times \frac{7}{2} \\ \\ \Rightarrow x =35$
