For a class gardening project 1/3 of mrs gordon's students planted marigolds and 1/2 planted tulips what fraction of the class planted either marigolds or tulips

Get them to have a common denominator so you can add them

(1/3) * 2 = 2/6 and (1/2) * 3 = 3/6

Add them together

(2/6) + (3/6) = 5/6

So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither
