The first bar is what percent as long as the second bar?

To find the how much the first bar represents from the second bar, we need to calculate the ratio between them.
[tex]\frac{2}{5}[/tex]To convert this ratio to a percentage, we just need to convert the denominator to 100, and the numerator will be the percentual value. We can convert by multiplying both the numerator and denominator by 20.
[tex]\frac{2}{5}\times\frac{20}{20}=\frac{2\times20}{5\times20}=\frac{40}{100}=40\%[/tex]The first bar is 40% as long as the second bar.
