There are 143 people in an audience. Out of this number, 63 are female. What percent of the people in the audience are male?

143-63=80. There is 80 males in the audience. So you divide 80 and 143:
80/143
then you multiply the answer by a 100:
(80/143)*100
80/143=0.55944055944
Multiply that number with a 100 which is 55.94
the answer 55.94% or you can simplify which is 56%
