First add the number of people in each ratikn together.
6+2=8
Now divide the total number of people by the number of people in each ratio to get how many ratios there will be.
80 divided by 8 = 10
Times the number of ratios by the number of girls in each ratio.
10x6=60
There are 60 girls.

This scenario can be expressed by the equation 6x + 2x = 80
first, add 6x and 2x because they are like terms
you are left with 8x = 80
divide both sides and we know that x = 10.
so, put 10 back into the original equation:
6(10) + 2(10) = 8
There are 60 girls and 20 boys :)
