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
Answer: 3 : 4
Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
