For this case we have that the total of the balls is 86. We know there are 8 footballs then:
Basketball: Two more than twice the number of footballs are basketballs, that is:
There are 18 Basketballs.
Baseballs: Four less than 5 times the number of footballs are baseballs, that is:
There are 36 Baseballs.
Softballs: Six more than half of baseballs are softballs. That is to say:
There are 24 Softballs
If we add we must get 86.
ANswer:

Three different interpretations of an 8% sales tax? Odd question.
8%, 8 percent, literally means "8 per 100". For each $100 item you purchase you pay an additional $8 in tax.
8% = 0.08, the factor applied to the price to determine the tax.
8%=8/100, you pay 8 cents in tax for every 100 cents in sales

Just because the ratio is 5:7 doesn't mean the total is 5+7=12. Non zero factors don't change a ratio, e.g. 5:7=50:70.

b/g=5/7
The fraction of boys is b/(b+g) which if you've done these a few times you can immediately write down as 5/12. Let's solve it like its our first time,
Similarly the fraction of girls is 7/12.
