There are 36 people at the meet
Step-by-step explanation:
if the ratio is 4 men to 5 women it means that every time there are 4 men there will be 5 women so its 4/5
and since we know there are 20 men the equation becomes:
4/5 = x/20
so to make 4/5 have 20 as a denominator we multiply by 4/4.
4/5*4/4 = 16/20
So, now we know there are 16 women.
And 16+20 = 36
