A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...

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.

Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.

A nonzero whole number is a quantity which does not equal zero and number without fractions.

You cannot: whole numbers and improper fractions are disjoint sets.

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.

This is done when subtracting mixed fractions. Here you subtract the whole part and the fractional part separately; but if you have a case such as, for example, 5 2/6 - 3 3/6 in the first number, you can "borrow" one whole, which in this case is equal to 6/6; that is, you subtract it from the whole part and add it to the fractional part, thus converting the subtraction to: 4 8/6 - 3 3/6 Now you should have no trouble subtracting the whole part and the fractional part separately.

add? dont you mean subtract?

No.

Subtract fractions and then subtract the whole numbers. Sometimes you may need to borrow from the whole number. Ex: 3 1/4 - 1 3/4 (3 1/4 would be written as 2 5/4) so the equation would be 2 5/4 - 1 3/4 = 1 2/4

fractions are parts of a whole number

A simple fraction is a fraction that is a whole number divided by a whole number. Complex fractions can have fractions inside of fractions.

Fractions are not whole numbers. They are fractions. You can call a fraction a whole number, but that doesn't make it one.

A nonzero whole number is a quantity which does not equal zero and number without fractions.
