each adult gets 1, each child gets 3

ratio is 1/3

1 x

-- = ---- ratio of adult to total, to find number of adults getting a sweet

4 240

4x = 240 cross-multiplied

x = 60 divided

That means there were 60 adults.

Ratio of adults to children is 2/1

If there were 60 adults, then there were 30 children.

If the boys and girls were the same, then there were 15 boys and 15 girls.

1.) 15/90 = 1/6 attending the party were (non-adult) girls

2.) 15 girls were attending the party
