To subtract an improper fraction from a whole number, turn the whole number into a fraction with the same denominator as the improper fraction. Then minus.
All whole numbers actually have a "1" as a denominator, we just don't write it (it's assumed.)
E.g 10 = (10/1) 20 = (20/1) etc... to change the denominator to the same as the improper fraction, multiply the whole number (that is now a fraction over "1") by the denominator of the improper fraction.
E.g Let the improper fraction be 17/4, and your real number be 20. From above, we know that 20 is the same as "20/1", with "1" as the denominator. You want this "1" to be "4", so multiply the real number by "4/4" (which is essentially multiplying by 1, so doesn't mess up how big the fraction is)
20/1 x 4/4 = 80/4. Now the denominators of both fractions are the same, you can minus the improper fraction from the whole number.
i.e 80/4 - 17/4 = 63/4 Which is actually 15 3/4 .

Are fractions whole numbers?
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
How do you write a whole number as imprper fractions?
You cannot: whole numbers and improper fractions are disjoint sets.
How do you subtract mixed numbers and borrow from the whole number?
you subtract mixed numbers by changing them to improper fractions. to borrow from a whole number you take away one like 5 changes to 4 and then you change look to the other mixed number your subtracting by and write its denominator as 4s denominator.
How do you subtract mixed numbers with regrouping?
you take away one of the whole number=then you add or subtract your fractions=
How do you do mixed numbers?
turn them into improper fractions
How do you subtract whole numbers with fractions?
Turn the proper fraction into an improper fraction.
Are fractions whole numbers?
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
What is a subtracting mixed number?
Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.
How do you subtract whole numbers by fractions?
Simplify them.
How do you subtract fractions from whole numbers?
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.
How do you write a whole number as imprper fractions?
You cannot: whole numbers and improper fractions are disjoint sets.
How are all integers and whole numbers are rational numbers?
Because they can be expressed as fractions albeit improper fractions
How do write a fraction as a whole number?
The majority of fractions will not be able to become whole numbers. Certain improper fractions, where the numerator is a multiple of the denominator, can become whole numbers. No proper fractions can.
How do you make a mixed number to a whole number?
Mixed numbers usually become improper fractions, not whole numbers.
How do you subtract mixed numbers and borrow from the whole number?
you subtract mixed numbers by changing them to improper fractions. to borrow from a whole number you take away one like 5 changes to 4 and then you change look to the other mixed number your subtracting by and write its denominator as 4s denominator.
How do you subtract mixed numbers with regrouping?
you take away one of the whole number=then you add or subtract your fractions=
Does the set of rational numbers include the set of whole numbers?
Yes because they can be expressed as improper fractions
