You can subtract the bigger fraction by the smaller fraction and then put a minus sign in front of the answer.

You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).

(-1/2) - (1/4) = -3/4 Done!

You need a common denominator; change the whole number into fraction form. If its a 1, and the fraction is 3/7 then you'd have to change the 1 to a 7/7 and then subtract that way. Although, you are likely to get a negative number.

Subtract the fraction of students who did from 1.

If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!

Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly

The answer is 1/8.

You change the mixed fraction to an improper fraction . Then you find the denominators GCF. Then you subtract. Another reply: Converting to an improper fraction is not really necessary, but converting to a common denominator is. Example: 3 1/2 - 1 1/3 = 3 3/6 - 1 2/6 = 2 1/6. In other words, you can subtract the integer part and the fraction part separately.

You convert the mixed numeral into an improper fraction. Now subtract the improper fraction from the whole number by putting the whole number over 1.

either convert the fraction into a decimal or the integer into a fraction. For example if you were attempting to subtract 1/3 from 2, you could either turn 1/3 into 0.3 repeating (by dividing 1 into three) or by turning 2 into 6/3, by placing the denominator from the fraction below the whole number, than multiplying the whole number by its new denominator, thus effectively converting it into a fraction. To subtract 1/3 from 6/3, simply subtract 1 from 6, and keep the denominator (5/3). If you opted to convert the fraction into a decimal earlier, simply subtract the 0.3 repeating from the 2, thinking of the 2 as its other representative, 2.0 repeating, solving to 1.6 repeating (ending eventually in an imaginary 7)

Just the fraction, 1/2. Or, you could subtract 1/2 from 1, or add 1/2 to 0. It's pretty easy.

1/3 = 3/9

In the same way that you would answer a fraction subtract another fraction. The result could be either positive or negative, just as is the case with negative whole numbers.

By changing the mixed number into an improper fraction and ensuring that they both have the same denominators simply then subtract one improper fraction from the other improper fraction.

well its simple here is an example 3/8-2/8=1/8 you leave the denominator the same and 3-2=1

I suppose you mean the fraction 4/5. Just subtract 1 - 4/5, which is the same as 5/5 - 4/5.I suppose you mean the fraction 4/5. Just subtract 1 - 4/5, which is the same as 5/5 - 4/5.I suppose you mean the fraction 4/5. Just subtract 1 - 4/5, which is the same as 5/5 - 4/5.I suppose you mean the fraction 4/5.

The recommended method in schools is to write the whole number as a rational fraction with denominator 1, and then proceed as you would for subtracting one fraction from another fraction.

In order to subtract a fraction from a whole number one should take the bottom number from a fraction, for example if the fraction was 1 10th then the bottom number would be 10. The whole number should be divided by the bottom number, then the top number equivalent removed from the total whole number and this will leave the fraction number once the fraction has been subtracted.

Change 1 to a fraction and subtract the numerators. EXAMPLE: 1 - 2/5 = 5/5 - 2/5 = 3/5

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...

Convert 1 to a fraction with the same denominator as the one you're subtracting. 1 - 2/5 = 5/5 - 2/5 = 3/5

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.

If denominators (bottom numbers) are the same,subtract numerators (top numbers).If not you need to make the denominators the same and then subtract numerators.

Pie charts make nice fraction diagrams. Each fraction that you subtract is equivalent to taking out a slice of pie.
