Given:

• 4/9 of students are Science Society members
• The rest are Mathematics Society members
• 2/5 of Science Society members are girls = 16 people

Find the number of Science Society members:

• 2/5x = 16
• x = 16*5/2 = 40

Find the total number of group members:

• 4/9x = 40
• x = 40*9/4 = 90
