lets say your fraction is 15/7. you have to recognize that the number 7 is your base number and it is what your whole fraction is based off of. your fraction is approximately equal to 2.14
this means you have 2 whole numbers and a fraction of a number left. if you look at 15/7 carefully you notice that two sevens equal 14. you have 15 which means you have one remainder. so you have 1 out of 7 remaining after you get two whole sevens out of 15.
so your mixed number is 2 1/7
take 21/6. there are three 6s in 21. so your first number in your mixed number is 3. three 6s is equal to 18. now you have 3 left over out of 6.
this mixed number is 3 3/6 or in lowest terms 3 1/2
take 31/4. there are seven 4s in 31. so your first number is 7 in the mixed number fraction. since seven 4s is equal to 28 you have 3 remaining out of 4.
this mixed number is 7 3/4
First you would want to change the mixed number to an improper fraction. Then you can subtract
You change them into improper or topheavy fractions.
I wouldconvert both to improper fraction,find a common multiple (CM),calculate equivalent fraction with CM as the denominator,add the numerators,change the improper fraction to a mixed fraction, if required,simplify the fractional part of the mixed fraction - if appropriate and required.
You don't.
change it to an improper fraction and then divide it
You do the numerator divided by the denominator, then simplify the fractions if you can. (this is how you change a improper fraction to a mixed number, you cannot change a proper fraction to a mixed number)
First you would want to change the mixed number to an improper fraction. Then you can subtract
You change it into an improper fraction, then simplify it, then if you want to, change it back to a mixed number.
If its not an improper fraction then you cant....
You change them into improper or topheavy fractions.

I don't think you can but, you can change an improper fraction to a decimal.

An improper fraction is a fraction. It can't become a proper fraction.
