My scribe post for the afternoon =)

This afternoon Harbeck was talking about Ratio....

In order to understand ration you have to understand what is a fraction? A fraction is part a whole...


Ratio
numertator/denominator = part/whole


1= 1:0, 8:0

3/4= 3:1, 3:4

1/2= 1:2, 1:1

2/5= 2:3, 2:1

1/3= 1:1, 1:2

1/4= 1:3, 1:4


Ratio tells how one number is related to another number. A ratio may be written as A:B or the phrase " A to B". A ratio of 1:5 says the second number is 5 times as large as the first. The following steps will allow determination of a number when one number and the ratio between the number given.


eg: Determine the value of B if A=6 and the ratio of A:B= 2:5


- Determine how many times the variable A is divisible by the corresponding portiong of the ratio. ( 6/2 = 3)


- Multiply this number by the portion of the ratio representing B (B*5=15)


- Therefore if the ratio of A:B is 2:3 and A=6 the B=5.


If any of you don't understand this here is a website that might help you understand it better:
