How do you share 17 subs between 22 people?

Please leave a comment behind at your class blog. What did these people do right and what would you change.

In your comment please talk about

  • fractions show division
  • the size of the whole matters
  • friendly and unfriendly fractions

Why change the question when it's not going to be equall?

Hello , and my comment is concerning the one where you changed the 17 / 22 into 7 / 12 . The size of the whole matters , don't just change the whole if its not going to be equivillant .

Allthe stragedy was good
But when they when some tries to do equivalent fractions its messes up the problem. In the picture some subs were not divided equally.
It's good when some tried using friendly's easier.

hey, my comments is about 17 / 22 into 7 / 12. the size of the whole matters , don't have to change the whole ifs not equivillant .

Hey Mr.H my comment on 8-41 fosnot1 is changing the fraction back to normal because when you divide 17 by 22 it is 0.77, but when you divide 7 by 12, it has a different amount than 17/22.

* fractions show division:
When u divide the top fraction by the bottom fraction, u get your answer in division.

* the size of the whole matters: When 1/2 is bigger than the other 1/2, that means depends on the size of the 1/2

friendly and unfriendly fractions: Friendly fractions r when fractions don't go on forever. Unfriendly fractions r when they go on forever.
I hope you get it Mr H

Fractions show division-You have to divide fractions or else there would only be wholes/(you divide to make a fraction), and you divide the bottom and top numbers to make a decimal

The size of the whole matters-the size of the whole matters because if person a.) gets 1/3 of a small whole sub, and person b.) gets 1/3 of a big whole sub then person a.) would not get an equal amount as person b.)

friendly and unfriendly fractions-an unfriendly fraction would be hard to do when dividing and trying to find the decimal/percent,it would have a decimal everytime you try to divide it in half,when you try to find two numbers to times together to get a certain number,the only number that you can times together is 1 and itself eg.,17,and when it goes on and on when you divide the numerator from the denomerator eg.,7.555555555 and so on.

A freindly fraction is easy to divide to make an equal number adn the dicimal/percent, it won't have a decimal when you try to divide it in half,when you multiply two numbers together to get a certain number,the only number you could divide together is 1 and itself eg.,6 ,and when you can divide the numerator from the denominator and it wont go on an on eg.,8

** to compare a fraction without a common denominator you can divide the denominator into the nummerator
example 1/2 = 0.5 > 1/4 = 0.25

** When you change the size of the whole you are comparing something to the fraction will be completely different like to compare half of this o to this O would not be accurate

**A friendly fractions is like 1/2 and unfriendly fractio nis like 89/157 which would you rather work with it would obviously be 1/2 because 1/2 is a much easier fraction.

**Fractions show division

Say you have 1/2
You can divide the numerator by the denominator, and would have 0.5

**The size of the whole matters

If you're dividing two different objects, one being about half the size of the other, and you divide those in half, you would obviously want the half of the bigger object. It would also be unfair to whoever was getting the other halves.

**Friendly and unfriendly fractions

If you were comparing fractions like 3/4 and 56/2034

3/4 would be the easier fraction to understand, therefore, it being the friendly one.

my comment is about turning 17/22 into 7/12 it matters if the wholes are equil and the size of the whole between those 2 fractions because 17/22= 0.7727 reapeating over the 27. While the 7/12= 0.583 the 3 is repeating so that means they are not equil

1. fractions show division because the denominator is the whole, and the numerator is that whole divided into that many pieces .

2. the size of the whole matters because if you were stranded on an island and you only had a peanut and a cucumber, and you cut both in half, you'd want the cucumber because its half is bigger .

3. unfriendly fractions are fractions with a larger numerator and denominator that can be reduced . for example, 1/2 and 5/10 . the 1/2 is just simply cutting an object into A HALF and taking one half, and 5/10 is cutting an object into 10 equal pieces and taking 5.

**** 17/22 can't be reduced into 7/12 . the size of the whole matters. & 7/12 would be smaller amount .
