how do you subtract fractions by whole numbers?
11690
When subtracting fractions from whole numbers, you need to change the whole number into a fraction. You then need to make a common denominator and then you can subtract the two numerators and you're all set.

To subtract mixed numbers, subtract the whole number parts of the mixed numbers and then subtract the fraction parts in the mixed numbers. Finally, combine the whole number answer and the fraction answer to express the answer as a mixed number. Subtract. Simplify the answer and write as a mixed number.

Subtracting mixed numbers from whole numbers requires you to change the whole number into a mixed number, making sure to give the fractions the same common denominator. Finally, subtract the whole numbers from each other and then the numerators of the fractions from each other and you are all done.

Subtract, don't add, the fractions. The correct answer is . Subtracting mixed numbers works much the same way as adding mixed numbers. To subtract mixed numbers, subtract the whole number parts of the mixed numbers and then subtract the fraction parts in the mixed numbers.

To subtract fractions with unlike denominators, rename the fractions with a common denominator. Then subtract and simplify. The LCM of 3 and 11 is 33 .
