Question

find the value of x 2:5=6: x​

Answer 1

Answer:

There are three different ways to represent a ratio:

a to b

a:b

a/b

So to solve your equation, rewrite the ratios:

6:5=18:x

6/5=18/x

Then cross multiply

18*5=6*x

Divide both sides by 6

(18*5)/6=x

Simplify

x=(18/6)*5=3*5=15

x=15

Answer 2

$\frac{2}{5} = \frac{6}{x} \\ \\ \\ = > 2x = 30 \\ \\ \\ = > x = \frac{30}{2} \\ \\ \\ = > x = 15$
