#17/21#

Explanation:

first find the lowest common denominator, in this case it would be 21 (7 x 3). 7 and 3 have no lower possibilities.

what we do to the bottom we must do to the top so since we multiplied the 7 in #1/7# by 3, we have to do that to the 1 as well. Same goes for the #2/3# - the 2 needs to be multiplied by 7.

#1/7 + 2/3#

#3/21 + 14/21#

#17/21#
