Two ideas are useful to keep in mind during the explanation that follows: Subtracting a negative fraction my college roommate was a math major, and she insisted on turning everything into a math challenge. And to get your denominator from 6 to 12, you have to multiply by 2.
Convert The Whole Number To A Mixed Number And Perform The Subtraction.
Simplify the fraction (if needed). Subtracting a negative fraction b from a positive fraction a means adding the number part of it (that means leaving the minus sign) to a. To subtract the fractions with unlike denominators, rename the fractions with a common denominator.
For Example If We Have To Subtract − 3 8 From 1 4 Means, Adding 3 8 To 1 4 Or 1 4 + 3 8 And As 1 4 Equal To 2 8, 1 4 + 3 8 = 2 8 + 3 8 = 2 + 3 8 = 5 8.
Now we add them using the following steps: Convert their symbols according to the above rule. Hence 1 4 − ( − 3 8) = 1 4 + 3 8 = 5.
