Answer 1

Question:-

If x: 15 :: 4:6, the value of x is ___ *

Answer:-

• The value of x is 10.

To find:-

• The value of x

Solution:-

$\large{\tt:\implies\: \: \: \: \: \: \: \: {}x :15 : : 4 : 6}$

$\large{\tt:\implies\: \: \: \: \: \: \: \: {} \frac{x}{15} = \frac{4}{6} }$

After cross multiplication,

$\large{\tt:\implies\: \: \: \: \: \: \: \: {}x \times 6 = 4 \times 15}$

$\large{\tt:\implies\: \: \: \: \: \: \: \: {}x = \frac{15 \times 4}{6} }$

$\large{\tt:\implies\: \: \: \: \: \: \: \: {}x = 2 \times 5}$

$\large{\tt:\implies\: \: \: \: \: \: \: \: {}x = 10}$

• The value of x is 10.

Answer 2

Answer:

=> x = 10

Step-by-step explanation:

Given that:-

$x:15::4:6$

To find the value of x,  

The given ratio is written as:

=> $\frac{x}{15}=\frac{4}{6}$

Now by using cross multiplication,

=> $x\times 6$ = $15\times 4$

Multiply the numbers, we get

=> 6$x$ = 60

Divide both sides by $6$, we get

=> $x$ = 10

Hence, the required solution is 10.

Hence, the required solution is 10.
