Question

If 5:12=30:X, then X=?
​

Answer 1

$\huge \mathfrak \pink{Answer}$

$\longrightarrow$ 5:12 can be written as $\sf\dfrac{5}{12}$

$\longrightarrow$ 30:X can be written as $\sf\dfrac{30}{X}$

According to the question:-

$\longrightarrow$ $\sf\dfrac{5}{12}$ = $\sf\dfrac{30}{X}$

$\longrightarrow$ 5x = 12×30

$\longrightarrow$ X = $\sf\dfrac{360}{5}$ = 72

$\longrightarrow$ X = 72.

Answer 2

Answer:

=> The value of X is 72.

Step-by-step explanation:

Given that:-

$5:12=30:X$

To find the value of x,

The given ratio is written as:

=> $\frac{5}{12}=\frac{30}{X}$

By using cross multiplication, we get

=> $5X$ = 30 $\times$ 12

Multiply the numbers, we get

=>  $5X$ = 360

Divide both sides by $5$,

=> $X = 72$

Hence, the required solution is 72.
