To find the fraction of all the people at the football match that are girls, we first need to determine the total ratio of boys to girls.

Since the ratio of boys to girls is 3:2, this means that for every 3 boys, there are 2 girls. Therefore, the total ratio of boys and girls is 3+2=5.

Next, we can find the fraction of girls by dividing the ratio of girls by the total ratio:

Fraction of girls = 2/5 = 0.4

Therefore, 40% of all the people at the football match are girls.
