3/8 of the people at a fun fair were children 3/4 of the remaining people were men there were 140 children than women how many people went to the funfair

This is the concept of algebra,

The fraction of children was: 3/8

fraction of adults was 1-3/8=5/8

fraction of men 3/4*5/8=15/32

fraction of women=5/8-15/32=5/32

Given that there was 140 more children than men, the fraction representing this will be:

(3/8-5/32)

=7/32

thus the total number of people will be:

1 / (7/32) * 140

=32/7*140

=640

the total number of people was 640
