You have to do KCF (Keep change Flip) Keep the first fraction change the - sign to a + then flip the numbers like 5/9 is now 9/5. =)
Subtract the numerators as we normally subtract them and then divide the resultant by the denominator. It's just simple like that.
The end result is: -2 + s
8t^2 - 11t - 4
subtract
You would subtract. For example, if you have 5-7, you would subtract the two like normal. And if you have 5+(-7) you would also subtract, because adding a negative number to a positive is the same as subtracting.
Express the mixed fraction as an improper fraction and then proceed as you would with ordinary fractions. If the answer is an improper fraction, then remember to convert to a mixed fraction.
Don't know what frations are. In fractions, 356 could be written as 356/1 or 712/2 etc.
no
none
288
The need for such concepts arises, among other things, from the manipulation of fractions. The least common multiple is commonly used to find a common denominator for different frations; this is required to compare, add, or subtract two (or more) fractions.
