To subtract a mixed number by a mixed number you first need to turn the fractions into improper fractions then you just subtract them as you would with the normal fractions

Turn the proper fraction into an improper fraction.

SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.

turn the whole number into an inproper fraction by doing this: multiply it by the denominator of the fraction.that answer is your numerator make the fractions denominator the whole number's denominator.then subtract just the numerators.you should have an improper fraction as your final answer, so turn that into a mixed number.

First, turn the fraction into a improper fraction. Then find a common denominator between the two numbers. After this, subtract strait across, but leave the denominator the same.

I think that the easiest way is probably (1) to convert to improper fractions, (2) then get a common denominator, (3) add or subtract, (4) reduce, and finally (5) convert back to a mixed number. That isn't what you are taught in school. In school you would (1) go straight to the common denominator then (2) see if it is possible to subtract, you don't have as many difficulties to consider in addition, then (3) you may have to 'borrow' 1 from a whole number and turn it into a fraction to make the denominator large enough to subtract, (4) subtract the whole numbers and subtract the fractions, (5) reduce the fraction as needed. In addition you just (1) get a common denominator (2) add whole numbers and fractions (3) reduce the fraction and in some problems change it into a proper fraction and increase the whole number.

you turn the " : " into "/"

you can't add nor subtract mixed fractions so you need to turn it into a fraction, if you wanna turn a mixed fraction into a fraction you need to multiply the whole number by the denominator, then add the numerator, then you can multiply normally (make sure you simplify and turn it into a mixed fraction your answer)

You have to turn the whole number into a fraction. Ex. 3= 3/1 Then get the fractions to have the same denominator. Ex. 3\1+1\3 becomes 9\3+1\3 Then add the numerators and you have your solution!

you can turn a whole number into a fraction by simply putting it over one like this 3/1 = 3 after you turn the whole number its just multiplying two fractions
