Remember? You know how to convert fractions to other equivalent fractions.
We can also reverse the process. Then it is called SIMPLIFYING:
Notice that both numerator and the denominator change, but the value of the
fraction |

1. Look at the pictures, and write down the simplifaction process. Also mark how many slices were joined or merged together and show the arrows and the division process like in the example.

2. Simplify the fractions. Draw pie pictures of the process.
|
|
|
| Look back and examine the exercises you have done thus
far.
What happens to the numerator and the denominator when you simplify? Discuss with your teacher. _________________________________________________________________________ |
|
Since you need to divide both the numerator and the denominator by
the same number,

3. Some of the following fractions are such that you CANNOT simplify them.
Cross them out. Why is that?
Discuss with your teacher. Simplify the ones you can simplify.

6. a) Tommy practices running, and he is
told to use 10 minutes for a warm-up before the practice, and 10 minutes for
stretching after the practice. All in all he uses one hour for the
warm-up, practice, and stretching.
What part of the total time is the warm-up time? What part of the total
time is the actual running practice time? (Remember to simplify the
result.)
b) Computer screen is 800 pixels
wide. A horizontal line is 600 pixels wide. What part of the screen
width does it take? (Remember to simplify the result.)
How wide should the line be if you want it to take up exactly 1/2 of the total
width of the screen?

P.S. ....
| Check out these short video clips from my favorite band - Rockabilly.US. They play oldies, Elvis, country, and top hits of the 50s and 60s. It's a show with large band, costumes, choreography, little skits, "Kid Kritters", 6 dancing/singing girls, junior dancer troupe, etc. | |
|
"Be My Baby" originally by the Ronettes |
Impossible Dream (Elvis song) |
| Most importantly, the band wants to use the uplifting and energetic music to bring some fun, happiness and encouragement into people's lives. They're doing it selflessly to help others, and don't get paid for any of it themselves. And I admire that! | |
