Vicky's First Growing Post

Which fraction is bigger? 1/2 + 1/6 + 1/4 + 7/12



1/2
First I divide 2 (denominator) into 12, which is 6. Then I time 6 to 5 mins, which gives me the answer, 30 mins.
2 ÷ 12 x 5 mins = 30 mins
You could do this in another way too.
Divide 2 (denominator) into 60 mins, which equals to the answer, 30 mins.
2 ÷ 60 mins = 30 mins

1/6
Same thing. 6 (denominator) divided by 12, is 2. 2 times, 5 mins is 10 mins.
6 ÷ 12 x 5 mins = 10 mins
Again, you could do this in another way.
6 (denominator) divded by 60 mins, equals 10 mins.
6 ÷ 60 = 10 mins.

Now, you add the answers.
30 mins plus 10 mins equal 40 mins.
30 mins + 10 mins = 40 mins (40 mins/60 mins)





1/4
4 (denominator) divided by 12 is 6, 6 times 5 mins is 15 mins.
4 ÷ 12 x 5 mins = 15 mins
Different way...
4 (denominator) divide by 60 mins is 15 mins.
4 ÷ 60 mins = 15 mins

7/12
12 (denominator) divided by 12 is 1, 1 times 5 mins is 5 mins, but look at the numerator '7', so 7 times 5mins is 35mins.
12 ÷ 1 x 5 mins x 7 = 35
Another way doing this...
12 (denominator) divded by 60 mins is, 35 mins.
12 ÷ 60 mins = 35 mins.

Then you add the mins,
15 mins + 35 mins = 50 mins (50 mins /60 mins)

Now lets compare.....
The first set of fraction is, 1/2 + 1/6. We found out it equals to 40/60.
The second set of fraction is, 1/4 + 7/12. We found out it equals to 50/60.

40/60 <>

(NO PHOTO OF BIKE RACE sorry.)

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.

Fraction Game Link:

This fraction game is pretty easy, its like a matching game. I just like the sound effects. ^^ It's funny.

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?

For 12th we divided it by 60 which equals to 5,
6th I divided it by 60 and it's 10.
3rd i divided it by 60 and it equals to 20.
The patterns i noticed were that, some of the numbers landed on the same KM, like : 20, 30, 40, ect...

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.

I can get 3/4 of a number by cutting 16 in half (8) then cut 8 in half (4) add both numbers , 4 and 8, and you get 12. 12 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.

Fraction Question, which is bigger? 9/12 + 3/4 or 2/5 + 4/6
Haha thats look so challenging ^^

Ok first, i divided 12 (denominator) to 60 mins, which is 5 mins, and i times it by 9 (numerator) and the answer is, 45 mins.
Next fraction, 3/4. I divided 4 (denominator) to 60 mins, which is 15 mins, and i times it by 3 (numberator) which is 45 mins.
Now i add the two mins, 45 mins plus 45 mins is 90 mins (90/60 or 1 30/60)

Next fraction, 2/5. 5 divided by 60 mins is 12 mins, 12 mins times 2 is, 24 mins.
Last fraction, 4/6. 6 divided by 60 mins is 10 mins, 10 mins times 4 is, 40 mins.
Now i add the last two mins, 24 plus 40 mins is, 64 mins. (64/60 or 1 4/60)
Ok let's compare.... 1 whole 30/60 > 1 whole 4/60

10) Mark your own Growing post and one other persons growing post. Use the following guide. Paste it in as a comment. Be honest. You may mark a persons work from another room. You may not mark a person's post that has already had a person mark it. Look before you comment.
