Question

The value of 20% of 2 is equal to …

Answer 1

Hint: First convert percent number into fraction form, then multiply it by the number given to find the desired result.

Complete step-by-step answer:
In the question, we have to find out the values of the given expression.
In the expression, % is called Percentage. Percentage is a ratio which is expressed as a fraction of 100. It is often denoted by using the ‘%’ sign. Percentage is dimensionless or pure number.
For example: 45% is read as forty five percent and is equal to ${\displaystyle \frac{45}{100}}=0.45$.
The percent value if computed by multiplying a numeric value of the ratio by 100.
Now to calculate the percentage for the given value, first we change the percentage to the fraction by dividing it with 100 and then multiplying the fraction with the number. So, as we are given we have to find 20% of 2, we will first change 20% to the fraction form, that is,
${\displaystyle \frac{20}{100}}={\displaystyle \frac{1}{5}}$
Now we will multiply the fraction with the given number, so we get
${\displaystyle \frac{1}{5}}\times 2=0.4$
So, the required answer is 0.4.

Note: Students should know about the meaning of the % sign, how to change it to fraction form. And also should know how to take percent values of the numbers. They should be careful about calculations.
Students generally make mistakes by not dividing the number by 100, as % is given here.
