Do you need a common denominator for all fractions before doing the order of operations?
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
How do you put different fractions in increasing order?
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
How do you know if a fraction is close to 1?
The higher to top number related to the bottom number will tell. Eg 67/80 is closer to 1 then 47/80 If you are to compare two fractions with different denominators (bottom number) then you'll need to convert them to a common demoninator. Eg 5/8 and 3/4 They would become 5/8 and 6/8 as the 6/8 is the bigger number it is closest to 1.
What you need to add or subtract fractions?
You need a common denominator in order to add or subtract fractions.
Do you use notation to compare and order fractions?
You can use the same notation and ordering for fractions as you do integers. The difficulty with fractions is that in most cases you need to find eqivalent denominators to see how they rank. Ie. If I said order for smallest to largest 2/3, 1/6, 72/96 and 24/48. It would be difficult without finding some similar base (is 2/3>72/96?). Instead if you conver them into a common base... 8/12, 2/12, 9/12, 6/12. Now you can easily order and/or compare the fractions.
What do fractions need to have to compare them?
The same numerator or the same denominator.
What are compatible numbers for fractions?
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
Do you need a common denominator for all fractions before doing the order of operations?
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
Why do you compare fractions?
To compare any two fractions they first need to be converted to numbers on a similar basis: Convert both to decimals: the smaller decimal is the smaller fraction. Find equivalent fractions with the same denominator: the fraction with the smaller numerator is the smaller number. Find equivalent fractions with the same numerator: the fraction with the larger denominator is the smaller number. I recommend that the last of these is used for integral reciprocals (comparing 1/2, 1/4, 1/7 etc) or by more proficient users.
Why is it easier to compare fractions with the same rather than denominator?
If the fractions have different denominators, you need to: 1) Convert to equivalent fractions with a common denominator, 2) Compare the numerators. If the fractions already have the same denominator, there is no need for the first step - which happens to be the most difficult step. Note that as a shortcut, you don't need the LEAST common denominator, any denominator can do. Thus, you can just use the product of the two denominators as the common denominator. As a result, to compare the fractions, you simply multiply the numerator of each fraction by the denominator of the other one, and then compare. However, this is still more work than simply comparing two numbers.
How do you use comparing mixed fractions?
Assuming the fractions are "normalized" (the fractional part is less than 1): First compare the integer part. If the integer part is the same, you need to compare the fractions. If the denominator of the fractions is different, you have to convert to a common denominator. The simplest way to find a common denominator is to multiply both denominators (i.e., you don't need the LEAST common denominator - any common denominator will do).
How do you write fraction from least to greastest?
You can compare two fractions by converting them to a common denominator - but if you need to compare several fractions, it would be easier to write each fraction as a decimal, with several digits after the decimal point, then compare the decimals. Oh Yeah And When I Have A Question No One Effen Answeres It!
Can The quotient of two fractions cannot be a whole number?
It can be but need not be.

What are some rules about comparing fractions with the same numerator?
It depends on how you need to compare them. If you want to know which one is larger, just look at the denominator - a smaller denominator means a larger number. If you need to add or subtract them, the only thing you can do is make the denominators equal.
How do you put fractions in ascending order?
You need to be able to compare two fractions at a time, to see which one is greater. One way to do this is to convert two fractions at a time to a common denominator. It need not be the least common denominator - any common denominator will do, therefore you can just multiply the two denominators. Another way to compare fractions is to convert them to decimal. This can quickly be done with a calculator.
What is the common denominator of 70?
For something to have a common denominator, you would need two fractions to compare with each other. e.g, 1/2 and 7/2 have a common denominator.The number 70 can have a denominator 1, i.e. 70/1 = 70. It could also be written as 140/2=70. You would need another fraction to compare it to.
