Princeton had a gender reveal party and invited all of his fellow employees to celebrate with him. If the total number of guests were 60, and 2/3 were male guests, how many female guests attended the party?

How many males were in the party? ** The number of males in the party was 2 males / 3 guests * 60 guests = <<2/3*60=40>>40 males
How many females were in the party? ** If the total number of people at the party was 60, then there were 60 guests - 40 males = <<60-40=20>>20 females.
