How do you do compare and order fractions and mixed numbers?
It may be simplest to convert them all to a common form: rational fractions, decimal fractions or percentages and then compare them. When you are more expert, you may be able to convert them pairwise into a common basis and compare.
How can you convert to proper fractions?
It depends on what you want to convert to proper fractions. Not all things can be converted to proper fractions.
How do mixed numbers become improper fractions?
While mixed numbers are the natural choice for spoken English (and are therefore well-suited to the answers of word problems), they aren't generally the easiest fractions to compute with. In algebra, you will almost always prefer that your fractions not be mixed numbers. Instead, you will use "improper fractions", or fractions where the top number is bigger than the bottom number. The standard way to convert a mixed number to an improper fraction is to multiply the bottom number by the "regular" number, add in the top number, and then put this on top of the bottom number as a new fraction. For instance, to convert 11/2 to an improper fraction, you do the following:I multiplied the bottom 2 by the "regular" 1, and then added in the 1 from on top, getting 3. Then I put this 3 on top of the 2 from underneath.

Remember that a fraction is just division. Divide the top number by the bottom number. Whatever you get on top of the division symbol is your "regular" number. Whatever your remainder is, put that number on top of the number you divided by. (To convert to mixed numbers, don't use decimals. Just find the quotient and the remainder. Then stop.)Convert to a mixed number.First, I do the long division to find the whole-number part (being the quotient) and the remainder:Since the remainder is 1 and I'm dividing by 4, the fractional part will be 1/4.
How do you find the sum of all fractions?
Make sure the denominators of all the fractions are common.Add all numerators.Reduce the final fraction to its simplest form.Convert improper fraction to mixed number if needed.
How do explain a mixed number into a decimal?
A decimal is one way of representing numbers which may be whole or fractions. So, a mixed number which by definition is a number, can be expressed as a decimal. That explains it all!
Why is it necessary to convert mixed fractions to improper fractions before multiplying or dividing?
Multiplying mixed fractions is very cumbersome and prone to errors. Therefore, it is prudent to convert them to improper fractions. Once that is done, you may simply find the product of all the numerators and divide that by the product of all the denominators. Then you convert back to a mixed number. And there are lots of tricks -- like "canceling out" -- that you can do to simplify the multiplication. Unfortunately, those techniques are very difficult to demonstrate here. It would not be even if it is not an improper fraction and that's why you have to convert
When is it necessaryto rename a mixed number when subtracting?
When doing sums with mixed numbers, it is often easier to convert the mixed numbers to improper fractions, do the sum and convert any resulting improper fraction back to a mixed number. This is especially true of division, but with subtraction, if the fraction part of the second mixed number is larger than the fraction part of the first mixed number (subtracting the second from the first), this will result in requiring borrowing from the whole number of the first mixed number. Using improper fractions avoids this complication and makes all sums easier.

How do you calculate the sum of fractions?
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
What is regular fractions?
The terms for fractions are common, improper and mixed numeral.Common fractions have a numerator that is smaller than the denominator.Improper fractions have a greater numerator than denominator.Mixed numeral has a whole number next to a common fraction.

Is 2.7064 rational or irrational?
This number is rational - all fractions, including decimal fractions and mixed numbers are rational.
Is mix number always greater than a whole number?
no. lets use 10,000,000,000,000, which is a whole number, and 1 1/2, which is a mixed number. all a mixed number is is a mix of fractions and whole numbers,
Should all improper fractions be converted to mixed fractions?
Yes they should
