### Jonah's First Growing Post

3.) Which set of fractions is larger 1/2 + 1/6 or 1/4 + 7/12?

1/4 + 7/12 is larger since 7/12 equals 35 minutes and 1/4 equals 15 minutes when you add them together you get 50 minutes.

4.) (Errors on getting the picture, so I couldn't get it)

5.) Jonah's and Megan's Bike Race (errors on getting the picture).

I think 1/4 + 7/12 is larger because since 7/12 is 35 minutes and 1/4 is 15 minutes if you add them you have 50 minutes altogether.

If you add 1/2 and 1/6 together which is the same as 30 minutes plus 10 minutes you get 40 minutes altogether.
To get the location of the water station which had to be every tenth of the way, I divided 60 (km, which is how long the race was) by 10 to see how many times 10 goes into 60. I found that 10 goes into 60, six times.

To get the location of the food wagon which had to be every fourth of the way I divided 60 by 4 to see how many times 4 goes into 60. I found that 4 goes into 60, 15 times. I got this question mixed up because I just divided 60 into 4.

To get the location of the juice and fruit station which had to be every fifth of the way I divided 60 by 5 to see how many times 5 goes into 60. I found that 5 goes into 60, 12 times.

To get the location of the resting points which had to every eighth of the way I divided 60 by 8 to see how many time 8 goes into 60. I found that 8 goes into 60, 7.5 times.

To get the location of the kilometer marks which had to be every twelfth, sixth, and third of the way I divided 60 by 12 only because 1/12, 1/6, and 1/3 are all common multiples of each other and 1/12 goes into to both sixth and third. I found that 12 goes into 60, 5 times; 6 goes into 60, 10 times; and 3 goes into 60, 20 times.

6.) Do a google search for fraction games. Find a good site and write a review of the game. Tell everyone what is good about this site. You also need to create a link to the site.

This is a good fraction game because since you have a limited amount of time to find the equivalent fraction and they are all mixed up it becomes confusing, especially with the time limit.

7.) Go back to your picture of the bike race. Tell us all about how you calculated the Km positions at a twelfth, sixth and a third. did you see any patterns?

Yes, I saw a pattern. I saw that twelfth and sixth both go into a third since they are factors or multiples of each other. Like 1/3 is equal to 4/12 and 2/6, that is the pattern.

8.) What are 2 different ways to find a quarter and 3/4 of a number? Use one of the following 16, 22, or 110.

One way to find 1/4 is: when you divide the number you want to find 1/4 of, which is 16 in this case, you divide it by the denominator which is 4. So it would be 16 divided by 4.

A second way to find 1/4 is: when you divide a number in half, like 16, you would get 8 then you divide into half again and you would get 4 which is 1/4 of 16, because half of a half is 1/4.

One way to find 3/4 is: the same way you find 1/4 and you just multiply the 1/4 by 3 to get 3/4.
( 16 divided by 4=4 then multiply. 4 multiplied by 3 is 12 which is 3/4 of 16.)

A second way to find 3/4 is: when you divide a number into half all you half to do is add half of the half to it. (16 divide by 2 (or half)=8. 8 plus 4 (which is half of 8)= 12, which is 3/4 of 16.)

9.) Write a fraction question and answer it. It has to be a question like one you have had on a test. You may answer it in pictorial or word form. The question I chose to do is, how to get 3/4 of 200.

I would do first divide 200 in 1/2, to get 100. Then I would add half of 100, which is 50, to 100 to get 3/4, since 1/2 is equivalent 2/4. So when you add then together you would get 150 which is 3/4 of 200.
