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

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.

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

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

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

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

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).

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

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.

The answer is 1/8.

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

1/3 = 3/9

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)
