11.

There are 14 pies in total. In each pie there are slices and 1/8 is one slice of each pie. This means 8/8 is a full pie ; 8/8=100% . From this we conclude that there are 8 pieces in one pie.

To find how many pieces there are in total we multiply the total amount of pies and the number of pieces in each: 14 * 8 = 112 pieces

4/8 , 1/4 , 1/2

We look at any fractions that can be simplified and 4/8 can be,

4/8 ; we divide both numbers by "2" and get 2/4 , we can do this again and get 1/2.

Now we have 1/2 ,1/4,1/2 .

To add fractions you must always have a common denominator ;

2/4 + 1/4 +2/4 ; because I see that 4 is the largest denominator out of the three fractions and i multiply the numerators by the number of times i multiplied the denominators for the others to get 4.

2/4 +1/4+2/4 ; you just add the numerators and get ; 5/4
