Answer 1

720=36=10/3

20/2x

answer is 10x

Answer 2

Given: 36x : 45 :: 16 : 2x

To Find: Value of the given equation.

Solution:

36x : 45 :: 16 :2x

It can also be written as,

$\frac{36x}{45} =\frac{16}{2x}$

Cross-multiplying the numerators and denominators, we get,

⇒ 36x $\times$ 2x = 16 $\times$ 45

⇒ 72x² = 720

⇒ x² = $\frac{720}{72}$

⇒ x² = 10

⇒ x = $\sqrt{10}$

⇒ x = 3.162

Answer: The value of x is 3.162.
