Boys : Girls = 3 : 5
3 + 5 = 8 parts
<u>Find 1 part:</u>
8 parts = 40 students
1 part = 40 ÷ 8 = 5 students
<u>Find number of boys and girls:</u>
3 parts = 3 x 5 = 15 girls
5 parts = 5 x 5 = 25 boys
Original Number of students = 15 : 25
<u>Find new ratio:</u>
New Ratio = 15 + 3 : 25 - 1 = 18 : 24 = 3 : 4
