i need help with proportions

Alright, well let's see.. 

An example of a proportion would be: 1/3 = 2/6

Therefore, you are kind of adding them together to make them equal to one another. 

1/2 = 2/4

1) Karl raised ducks for a living. He has 80 male ducks and 65 female ducks. If he sells 35 ducks, what is the percent of all the duck that he will sell?? 

2) Mr. Rono, a salesman, sold a television for $10,500. He was given 15% of the selling price of the television set. How much was his commission?

3) How do u exactly get the proportion and the percentage? And are the two things different?

 

Answers: 

definition: 
ratio = part/whole 

proportion is the ratio 
proportion = ratio = part/whole 

percentage = (ratio * 100) % 

proportion and the percentage mean almost the same thing, but are expressed in different ways. 

1. example: 
male duck = 80 
femal duck = 65 
so, total (or, whole) = 80 + 65 = 145 
ducks sold (or part) = 35 

Proportion of ducks sold = 
ratio = part/whole = 35/145 = 0.2414 

percentage of duck sold = (ratio * 100) % 
= (0.2414 * 100) % 
= 24.14 % 

2. 
tip: 
15% means 15 /100, so 15% = 15/100 

selling price = 10500 
commision = 15% of (selling price) 
means 
commision = (15/100) of (selling price) 
commision = (15 /100) * (selling price) 
commision= (.15) * (10500) 
commision= 1,575

 

I hope I helped, and have a wonderful day.

Mind blowing. 5 Stars from me!

Excellent!!
