We need to determine the value of 20% of 2.

First we will rewrite the percent as a fraction of 100.

We know that A% = A/100

==> 20% = 20/100

Now let us simplify the fraction by dividing both numerator and denominator by 20.

==> 20/100 = 1/5.

20% of 2 = 20% * 2 = (1/5)*2 = 2/5

Then, the exact value of 20% of 2  = 2/5 = 0.4

This is simple multiplication. To change 20% to a decimal drop the per cent sign and move the decimal two places to the left =.20; Then multiply .20 by 2.0 (since 2 is a whole number) the answer is .4

[Note that the answer to the question "What is x percent of y" is just x * y / 100.]

A percentage is a shorthand way of saying 1/100. So, 20% = 20 * 1/100 = 20/100 = 0.2

You can answer this question by comparing ratios: what number x of 2 is the same ratio as 20/100? Or,

x/2 = 20/100

x/2= 0.20

x = 0.20 * 2  = 0.40

Percent is a form of indicating per 100.

20% means 20 per 100 or 20/100 or 0.2

20% of 2 is 2* 0.2 = 0.4

Therefore 20% of 2 is 0.4

20/100 = 1/5 (you can simplify by dividing both numerator and denominator by 20 and you'll get 1/5)

---> 1/5 * 2 = 0.4 or .4

 

Good Luck!

20/100 = x/2 Equation

40 = 100x Multiply 100 by X and 2 by 20

x = 0.4 or .4

20% of 2

To find what 20% of 2 is, you have to use the equation

X/2 = 20/100 now multiply 20 with 2 and 100 with " x " 

By multiplying, you should get 

40 = 100x now divide 100 on both sides

By dividing, you should get 

40/100 = x simplify

x = .4 which is your answer
