Answer 1

Answer:

Yes


`(2)/(5) \: matches \: 40\%`

Step-by-step explanation :

To change a fraction to percentage, multiply the fraction by 100%

This implies that


`(2)/(5) * 100\%`
We cancel out the common factors to obtain,


`2 * 20\%`

This simplifies to



`= 40\%`

Hence


`(2)/(5) \: matches \: 40\%`

Answer 2

Yes, the third option (40%)

Explanation:

Given the fraction with numerator 2 and denominator 5:

`(2)/(5)`

You can convert it from this fraction form to a decimal number by dividing the numerator 2 by the denominator 5, obtaining the decimal number:

`(2)/(5)=0.4`

Finally, to rewrite this decimal number to percentage, you need to multiply it by 100. Then:

`0.4*100=40\%`

Therefore, there is a percentage that matches the fraction
`(2)/(5)`. This percentage is 40%, which corresponds to the third option.
