Answer 1

Answer:

Value of x = 21.33

Step-by-step explanation:

According to the information provided in the question it is given as

27:9::64:x

We need to find the value of x

Here as per the question it is seen that this is the ratio problem in which one set is equal to next set but set one have both values and in set two one quantity is given and need to find the second quantity  as x

This is a question from ratio and proportion

The simple concept here is

Product  of Extremes =Product of means

27:9

64:x

Now by simple cross multiplication we get the value of x

$27 x= 64\times 9\\27 x= 576\\x = \frac{576}{27} \\x= 21.33$

Hence value of x is 21.33

Answer 2

Question:-

• 27 : 9 : : 64 : x , find the value of x.

To Find:-

• Find the value of x

Solution:-

$\sf\implies \: 27 : 9 : : 64 : x$

$\sf\implies \: \dfrac { 27 } { 9 } = \dfrac { 64 } { x } ( \: cross \: multiply \: )$

$\sf\implies \: 27x = 64 \times 9$

$\sf\implies \: x = \dfrac { 64 × 9 } { 27 }$

$\sf\implies \: x = \dfrac { 64 } { 3 }$

$\sf\implies \: x = 21.3$

Hence ,

• The value of x is 21.3
