1. Some boy scouts helped traffic policemen. For every 3 policemen, there were 8 boy scouts. If there were 48 boy scouts how many traffic policemen were there?
2. Karl raises ducks for a living. He has 80 male ducks and 65 female ducks. If he sells 35 ducks what percent of all the duck will he sell?
Can you also explain how to get the answer?

Hello
1. 3/8 = x/48 so x = 3*48 / 8 = 18
2. 80 + 35 = 115 so 35/115 = 30.4%
Hope This Helps!!

1. This is a ratio problem. For every 3 policemen , theres 8 boyscouts. 3 / 8 is equal to x / 48 to find x, cross multiply to get your answer of 18 trafic policemen.
2. This is a percentage problem. First, look at what the problem asks. It wants a percentage of ducks, and their gender does not matter. So add the male and female ducks together which is 145. Then ask yourself this question... 35 (sold ducks) is what percent of 145? Heres the equation u lookin for. x / 100 = 35 / 145 cross multiply and get 24%

1. 1648/3 = 16
2. 24%
(80+65=145)145 x .24 = 35
They're probably wrong, but I'm the Grammar Police, not the Math Wiz.

1let them be x
x/3 =48/8=6
x=18 answer.
2.80+65=145= total number of ducks
number sold=35
% of ducks sold=35/145x100=700/29=24.14. answer

I can answer question #1 but #2 is too hard.It is 16 because 16x3=48 so 16 policemen.
