Chapter 7: Q9. (page 247)

Find the value of x.
$\frac{x}{4} = \frac{3}{5}$

Short Answer

Expert verified

The value of X is $\frac{12}{5}$ .

Step by step solution

Step 1. Given information.

The ratio here given is,

$\frac{x}{4} = \frac{3}{5}$

Step 2. Concept and Formula Used.

The properties of proportion,

if $\frac{a}{b} = \frac{c}{d}$ then, $a d = b c$

The given ratio is $\frac{x}{4} = \frac{3}{5}$ ,

Step 3. Use the property of proportion, if ab=cd then, ad=bc.

Then,

$5 x = 12$

Step 4. Divide both sides by 5.

$\begin{array}{l} \frac{5 x}{5} = \frac{12}{5} \\ x = \frac{12}{5} \end{array}$

Therefore, The value of X is $\frac{12}{5}$ .
