still negative for example -6/12 reduces to -1/2 the sign does not change
A fraction is really the numerator divided by the denominator. When you divide two negatives together you get a positive, so, you automatically change it to positive.
If the fraction is already positive, then it is also the absolute value. If the fraction is negative, just change the sign and it becomes the absolute value. Absolute value means the magnitude (value) of the fraction without any sign attribute.
Take the reciprocal of the fraction (flip it over). Then change the power to its positive equivalent.So, for example, (2/5)^-3 = (5/2)^3 = 125/8.
Not if the fraction is positive. But yes if the fraction is negative. Study the rules of multiplication and division by integers, and you wil see why. Multiplication by a fraction is simplty multiplication by one integer followed by division by another (or the other way round).
A fraction is a ratio
what is 0.28 as a fraction
you can change a fraction to a decimal by dividing the bottom number into the top number.
The same way you do a positive one except you put a dash in front of it!

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.
a fraction is already a fraction i don't mean to be mean but you must be super stupid.
To change 0.56 into a fraction, write it as a fraction and then simplify the fraction: 0.56 = 56/100 = 14/25
