The answer to the Fraction Riddle is:

1/4

To solve the riddle:

First add up the pieces you have:
 
1/2 +1/8 +1/8

To add these fractions you need to have a common denominator.

1/2 can be changed to 4/8

So  4/8+1/8+1/8 = 6/8

To make one whole you need 8/8

So 8/8 - 6/8 = 2/8

which you can simply or reduce to 1/4

 

To check your answer:

1/4 is = to the two 1/8 pieces.

 

So 1/4 is the answer to this week’s riddle.
