Fractions about math

Question

11/12 -5/12

 

Answer 1

Hi Chanequa.

 

With adding and subtracting fractions, the "bottoms" must all be the same.  In math-speak that would be, all of the fractions must have a common denominator.

 

Since both of your fractions have a "bottom" number of 12, you are all set.  This denomiator will NOT CHANGE throughout the whole subtraction process.

 

Once you have a common denominator, now do what ever the numerator (top) is asking, in this case, SUBTRACT.

 

So

 

11      5                 11 - 5

---  - ----   =     ------------  =

12      12                   12

 

 

6          1

--- = ------

12         2
