There are 1493 men and 1438 women in the audience at a concert. What is the percentage of the audience that are men
Advocard [28]
To calculate this answer you have to sum up the amount of women and amount of men at the concert: 1493 + 1438 = 2931.

Now you have the total amount of people. To get the precentage of the audience that are men, you do this: 1493/2931. (you divide the amount of men with the amount of every person present). 

1493/2931 = 0.5093

you multiply 0.5093 by 100

and you get 50.93%. And that is the final answer.
