Question

There are 99 males and 121 females participating in a marathon. What percent of the participants are female?​

Answer 1

To do this, we first want to see how many participants there are in total by adding both males and females.

`99+121=220`

Now we know that there were 220 total participants, but only 121 were females.

This allows us to set up the fraction 121/220= the percent female.

`(121)/(220) =0.55`

or 55%
