1/20 of the people at a performance are women 3/40 of the people are men the rest of the people are children what percentage of the people are children

To find the percentage of people who are children, we first need to determine the combined percentage of men and women in the audience.

The percentage of women is given as 1/20 of the total number of people. This means that the total percentage of women is 100% x (1/20) = 5%.
Similarly, the percentage of men is given as 3/40 of the total number of people. This means that the total percentage of men is 100% x (3/40) = 7.5%.

To find the percentage of children, we subtract the combined percentage of men and women from 100%:

100% - (5% + 7.5%) = 100% - 12.5% = 87.5%

Therefore, 87.5% of the people at the performance are children.
