Question

find the value of x in 4:9::8: x​

Answer 1

Answer:

18

Step-by-step explanation:

4:9::8:x

4:9=8:x

(If you want to change the numbers in the numerator and denominator, but keep the value same, you have to multiply the numerator and denominator with the same number. *4 is multiplied by 2, so 9 has to be multiplied by 2)

4:9=8:18

4:9::8:18

∴x is equal to 18

Answer 2

Answer:

=> The value of x is 18.

Step-by-step explanation:

Given that:-

$4:9::8: x$

We have to find the value of x,

The given ratio is written as:-

=> $\frac{4}{9}=\frac{8}{x}$

By cross multiplication we get

=> 4 $\times$ $x$ = 8 $\times$ 9

Multiplying the numbers, we get

=> 4$x$ = 72

Divide both sides by $4$, we get

=> $x = 18$

Hence, the required solution is 18.
