What ks the % of 4 = 2

Fittoniya [83]

Answer:

$50\%$

Step-by-step explanation:

Let x be the percentage then...

$x\%(4)=2$

Start by dividing both sides by 4:

$x\%=\frac{2}{4}$

Simplify the fraction:

$x\%=\frac{1}{2}$

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

$x\%=\frac{1}{2}*\frac{50}{50}\\x\%=\frac{50}{100}\\x=50\%$
