Blog on Blogging (BOB) for Ratios 10/20/09

During class today, we were doing ratios. Since there is a test tomorrow, we were told to do a BOB today for extra marks on the test. I chose this picture for my BOB because it is the simplest and is neatly organized.



O.K. lets make some ratios.

------------------------------------------------------------------------------

Part to Part Ratios :

6:6

Lighter Crayons to Darker Crayons

The Spring Green, Silver, Salmon, Yellow Green, Sky Blue, and Yellow Orange would go to the lighter side.

While Cadet Blue, Turquoise Blue, Green, Wild Strawberry, Purple Mountain's Majesty, and Gold would go to the darker side.

So it would be: Six lighter crayons compared to six darker crayons.

-------------------------------------------------------------------------------
2:3

Red Crayons to Green Crayons

Salmon and Wild Strawberry would be the reds.

Spring Green, Yellow Green, Green would be the greens.

So it would be: Two red crayons compared to three green crayons.

------------------------------------------------------------------------------
4:7

One word crayons to two word crayons.

Silver, Salmon, Green, and Gold would be the one word crayons.

Spring Green, Yellow Green, Sky Blue, Yellow Orange, Cadet Blue, Turquoise Blue, and Wild Strawberry would be the two word crayons.

So it would be: Four one word crayons compared to seven two word crayons.

------------------------------------------------------------------------------




Part to Total Ratios:

------------------------------------------------------------------------------
2:12

Red Crayons to All Crayons

Salmon and Wild Strawberry would be the reds and the rest are the total.

So it would be: Two red crayons compared to the total amount of crayons.
------------------------------------------------------------------------------
6:12

Light Crayons to All Crayons

The Spring Green, Silver, Salmon, Yellow Green, Sky Blue, and Yellow Orange would go to the lighter side.

So it would be: Six lighter crayons compared to all crayons.
------------------------------------------------------------------------------




Three Part Ratios:

------------------------------------------------------------------------------

2:3:3

Red to Blue to Green


Salmon and Wild Strawberry would be the reds.

Cadet Blue, Turquoise Blue, and Sky Blue would be the blues.

Spring Green, Yellow Green, Green would be the greens.

So it would be: Two red crayons compared to three blue crayons compared to three green crayons.

------------------------------------------------------------------------------

6:4:2

Lighter Crayons to One word crayons to Yellow Crayons.

The Spring Green, Silver, Salmon, Yellow Green, Sky Blue, and Yellow Orange would go to the lighter side.

Silver, Salmon, Green, and Gold would be the one word crayons.

Yellow Green and Yellow Orange would be the yellow crayons.

So it would be: Six lighter crayons compared to four one word crayons compared to two yellow crayons.

Question One:
Create another group/category for the crayons.
