Question

45%, 15%, 40%, 80%, 65%, 30%, 90%, 25% Do any of these percentages match the fraction 2/5?

Answer 1

Answer:

Yes, the third option (40%)

Step-by-step explanation:

Given the fraction with numerator 2 and denominator 5:

$\frac{2}{5}$

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:

$\frac{2}{5}=0.4$

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 $\frac{2}{5}$. This percentage is 40%, which corresponds to the third option.

Answer 2

Answer:

Yes

$\frac{2}{5} \: matches \: 40\%$

Step-by-step explanation :

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

This implies that

$\frac{2}{5} \times 100\%$
We cancel out the common factors to obtain,

$2 \times 20\%$

This simplifies to


$= 40\%$

Hence

$\frac{2}{5} \: matches \: 40\%$
