by a 6th grader-----------------------------------------------------------------------------------------------find # that is a common multiple of 2 and 7 - the denominators ( 14 )
then do:
denominator stays same - if improper fraction change to mixed #
1 times 7 = 7 + 3 times 2 = 6
2 times 7 = 14 7 times 2 = 14
6 + 7 over 14 is 13 over
14
if possible and needed - change to simplest form
