Question

Given that 5x:9=7:3 Calculate the value of x.

Answer 1

Answer:

x=21/5 is your correct answer.

Answer 2

Answer:

=> The value of x is $\frac{21}{5} .$

Step-by-step explanation:

Given that:-

$5x:9=7:3$

To find:- The value of x,

To solve this, we have to use the transposition method:  

As we have,

=> $5x:9=7:3$

The given ratio is written as:

=> $\frac{5x}{9}=\frac{7}{3}$

Now, multiply both the sides by $9$, for eliminating the denominator:

=> $\frac{5x}{9}\times 9=\frac{7}{3}\times 9$

Simplifying it further, we get

=> $5x=\frac{7}{3}\times 9$

Multiply the numbers,

=> $5x = 21$

Divide both sides by $5$, we get

=> $x = \frac{21}{5}$

Hence, the required solution is $\frac{21}{5} .$
