Question

x by 4 into x by 9 is equal to 1 by 5 solve

Answer 1

This should be your answer.

Answer 2

Let see your answer !!!!!

$\frac{x}{4} \times \frac{x}{9} = \frac{1}{5} \\ \\ = > \frac{x ^{2} }{36} = \frac{1}{5} \\ \\ = > 5x ^{2} = 36 \\ \\ = > x ^{2} = \frac{36}{5} \\ \\ = > x = \sqrt{ \frac{36}{5} } \\ = > x = \frac{ \sqrt{36} }{ \sqrt{5} } \\ \\ = > x = \frac{6}{ \sqrt{5} }$

By rationalization

=> x = 6/√5

=> x = 6 × √5 / √5 × √5

=> x = 6√5/5
