This video has a review of what we worked on in class on Friday - multiplying fractions by a whole number. Pay attention to his trick for figuring out if a fraction is 'proper' or 'improper.' Kind of a funny way to think about fractions.
Can you think of a time when this example might not apply?
Here are some videos to help you with:
understanding fractional pieces (watch this first) and comparing and ordering fractions.
Here is another option for a way to compare fractions using decimals (great if you want to check your work with a calculator).
What can you say about several fractions with the same numerator but different denominators?
What can you say about several fractions with the same denominator but different numerators?
Which way do you prefer to use to compare and order fractions?

ReplyDeleteIf you are comparing fractions with the same numerator you have to look at the denominator to determine which is a smaller fraction and which is the larger fraction. The bigger the denominator, the smaller the fraction.The smaller the denominator, the bigger the fraction.
If you are comparing fractions with the same denominator you have to look at the numerator to determine which is the smaller fraction and which is the larger fraction.The bigger the numerator, the bigger the fraction.The smaller the numerator, the smaller the fraction.
I like to get the same denominator by getting a common multiple and then looking at the numerator to determine which fraction is bigger and which is smaller.
What can you say about several fractions with the same numerator but different denominators?
ReplyDeleteYou cannot add them because to add fractions you need a common denominator, same thing applies when subtracting.
What can you say about several fractions with the same denominator but different numerators?
It's easy to add subtract and see which fraction is greater, also to order them.
Which way do you prefer to use to compare and order fractions?
Finding a like denominator so I can easily compare and order the fractions.

Less time when multiplying
ReplyDeleteI think its easier so that you don't have to change all of them to be thesame
I like the denominators to be the same because its easier to figure out and no hassle rose r 18
1)Can you think of a time when this example might not apply?
ReplyDelete2)What can you say about several fractions with the same numerator but different denominators?
They require more effort to compare and order fractions because you have to get the denominators of each fraction the same.
3) What can you say about several fractions with the same denominator but different numerators?
They are easy to order and compare the fractions because all you need to do is add the fraction then make it into a proper fraction.

ReplyDelete1.These are called unit fractions when comparing them greater the denominators smaller the fraction
2.greater the numerator = more of the fration (bigger fraction)
3. Which way do you prefer to use to compare and order fractions? Doesn't matter.

ReplyDelete1.If the numerator is the same and the denominator is different you can just tell whatis the same.
2.you would divide
3. both

ReplyDeleteWhat can you say about several fractions with the same numerator but different denominators?
If the fraction has denominators and the same numerator you look at the denominators to figure out if the fraction is more than or less than the other fraction.
What can you say about several fractions with the same denominator but different numerators?
If the numerators are different and the denominators are the same you have to look at the denominator to figure out if the fraction is more than or less than the other fraction.
Which way do you prefer to use to compare and order fractions?
I prefer to compare the denominator to the denominator because i know that the higher the denominator is lower the fraction value is.
I prefer comparing fractions with the same denominator because you just have to look at the numerator to find out greatest to least or least to greatest
ReplyDeleteI dont know what you can really do if the numerators are all the same but if the denominators are the same it is way easier to compare fractions

ReplyDeleteA time that might not apply is when you are multaplying a number times a fraction with more that one whole.
If you have thue same numerstet then all yiu need tovdo is make the dinsnanaters the sane so it easy to do anything with it is called a unit fraction
You can do anything very easy because you don't need to davide anything you and already there
Not if you have whole with
ReplyDeleteextras
Make the bottom the same so you can do what ever you need to

ReplyDeleteCan you think of a time when this example might not apply?
A time when this might not apply would be when the question asks to leave it as an improper fraction.
What can you say about several fractions with the same numerator but different denominators?
Several fractions with the same numerator but different denominators do have the same numerator, but if the denominator is larger the fraction piece is smaller and vice versa.
What can you say about several fractions with the same denominator but different numerators?
Several fractions with the same denominator but different numerators are easiest to compare because you can see if the numerators are bigger or smaller than the other. Then, since it has the same denominator, you can just see which one is bigger like you normally would with whole numbers.
Which way do you prefer to use to compare and order fractions?
I prefer to use to compare and order fractions by, if I can, turning them in to mixed numbers, so than I can use the whole number to make it easier to order.
