Question

4r- 2 = 14
4r -2 +2 = 14 + 2
   4r = 16
    4      4
       r = 4

Verify

4r - 2 = 14
4(4) -2 = 14
16 - 2 = 14
   14 = 14

step 1.  Make sure the bottom number ( the denominator ) are the same .
step 2. add the top number ( the numerator ) put the answer over the denominator .
step3. simplify  the fraction ( if needed ) .



Example 1.
   
                                       1/4 + 1/4= 2/4= 1/2


Example 2.
 
                                        1/3 + 1/6=2/6= 1/3


Example 3.simplify the fraction

                                        3/6=1/2

Stephen's Proportion Post

Part 1:

• proportion-the relationship of two variables whose ratio is constant
• ratio- relationship between two numbers of the same kind
• rate-a specific kind of ratio, in which two measurements are related to each other

Part 2:

1. 5 hours to travel 360 kilometers is about _____km/h. The answer is 72km/h

2.Emma saves 28 cents of every dollar that she earns.  Emma earned $75 last week.  How much money did Emma save last week? The answer is 0.28*75= $21 . Emma save $21 last week.

Part 3:
What are the three ways you can prove that equivalent ratio statements are true?
3/4 = 12/16  or 4/9 = 16/32

1.) There are equivalent fraction because 3/4 * 4 = 12/16
2.) 4/9 is not equivalent because 4/9 * 4 = 16/36.
3.) If you use cross multiplication 3/4=12/16 there both 48.

Part 4:
Find a video about using proportion and embed it in your post.  Make sure you select the small size of the video. (Bonus Marks if you make your own video about proportion and embed it)

Part 5:

1. Does this seem fair? No 
2. With what you know about proportion look and read what is in the image above.  Does it seem just and fair? 
3. Why have you made this choice? 
4. What would you have done if you were the judge?
