Why can you multiply a fraction by another fraction that has the same numerator and denominator and get a fraction that names the same amount as the original fraction?

You cannot because it is not true - unless the fraction is 0/n (for any n) or n/n = 1.

Which fraction has the same value and look different?
The fraction that you get when you multiply the numerator and denominator of the original fraction both by the same number.
How do you rationalizing the denominator?
Generally, the process involves multiplying the numerator and denominator of the fraction by the same number. This number is selected so that the original denominator becomes rational. In the process the numerator may become rational. If the original denominator is of the form √b then you multiply the numerator and denominator by √b/√b. If the original denominator is of the form a+√b then you multiply the numerator and denominator by (a-√b)/(a-√b). NOTE change of sign. There is a similar process, using complex conjugates, if the denominator is a complex number.
Can a fraction and a whole number be divided?
Yes. If you mean dividing a whole number INTO a fraction here is how you do it. Take the whole number and write it as a fraction where the whole number is the numerator (top part of the fraction) and the number "1" is the denominator (the bottom part of the fraction). Now, turn that fraction upsides down so that the "1" is on top and the whole number is on the bottom. Multiply the numerator of the original fraction times the "1" giving you the original numerator as the new numerator. Multiply the whole number times the original denominator giving you the new denominator. If you means dividing the fraction into the whole number it is similar. Write the whole number as a fraction (as above) with 1 in the denominator. Then flip the fraction over and multiply the two numerators, the two denominators and you have your answer.
How do yo turn a mixed number into a decimal?
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. To convert a fraction to a decimal, divide the denominator into the numerator.
How do you convert a mixed fraction into a fractional notion?
Multiply the denominator by the whole number, add that total to the numerator, put the whole thing over the original denominator.
How do you write a mixed number to a fraction?
You multiply the denominator by the whole number, then add the numerator of the original fraction to get the numerator of your new fraction. The denominator stays the same as the original. Then you simplify into lowest terms.
How do you write mixed numbers as an inproper fraction?
Multiply the denominator by the whole number, then multiply that by the numerator. Put that answer over the original denominator.

How do you change a mixed number with an improper fraction?
Multiply the denominator by the whole number, add the numerator and put that total over the original denominator.
How do you rename a mixed number as a fraction?
Multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.

How do you multiply a whole number by an improper fraction?
The same way as multiplying a whole number by an ordinary fraction: Multiply the numerator (top number) by the whole number and put it over the original denominator (bottom number). This can then be simplified by dividing the numerator and denominator by their highest common factor; or it can be converted into a decimal (which could be a whole number) by dividing the numerator by the denominator.
How do you make a mixed number in to an improper fraction?
The mixed number consists of a whole number and a fraction. Multiply the denominator of the fraction portion by the whole number and to this product add the numerator of the fraction portion. This value is the numerator of the new improper fraction. The denominator of the new improper fraction is the same as the denominator of the original fraction portion of the mixed number.
How do you convert mixed numbers to fractions?
To convert an improper fraction to a mixed number, divide the denominator into the numerator. The answer is the whole number. Put any remainder over the original denominator to create the fraction part.
