ooops yes there supposed to be multiplied

anonymous · Answer

with cancellation it is as follows :

 7      3
-- * ---   Here we can cancel 3 and 9 by dividing both by 3
9        4


 7      3         7       1           7
-- * --- = --- * --- = -----
 9      4         3       4          12
