Answer 2

Answer:

4% of a number​ is 8.

Step-by-step explanation:

Given 2% of a number is 4.

Let the number be x.

A percentage is a dimensionless number, is a number expressed as a fraction of 100.

Then 2% of x can be written as

$\dfrac{2}{100}~ \mbox{of}~ x=\dfrac{2}{100} \times x$

Thus,

$\dfrac{2}{100} \times x=4$

Multiplying both sides with 100

$\implies {2} \times x=4\times{100}$

Dividing both the sides by 2

$\implies x=\dfrac{4\times{100}}{2}$

         $=2\times100=200$

Then given to find 4% of the number​.

Thus,

$\dfrac{4}{100} \times 200=4\times 2=8$

Therefore, 4% of a number​ is 8.
