2/5 of a number is what percentage of that number?

Law Incorporation [45]

Answer:

40%

Step-by-step explanation:

In order to find percent, you can set up the fraction 2/5 to the equation x/100.

$\frac{2}{5}=\frac{x}{100}$

Then solve using algebra to cross-multiply.

$(2*100)=(x*5)$

$200 = 5x$

$x = \frac{200}{5} = 40$

so the answer is 40%.
