Question

Express the fraction as a percentage use the bar notation if necessary

Answer 1

We have to express the fraction as a percentage.

We can think of the percentage as a fraction with denominator 100.

This means that 25% is equivalent to 25/100.

This is because 100% is the unit, then 100/100 = 1.

We can use this to convert a fraction to a percentage by transforming the denominator into 100.

In this case, the fraction is 2/5.

The denominator is 5, so to convert it to 100 we have to multiply it by 100/5 = 20.

Then, we apply this both to the numerator and denominator:

`(2)/(5)*(20)/(20)=(2*20)/(5*20)=(40)/(100)=40\%`

Answer: 2/5 = 40%
