Question

Front and back row tickets to a performance are available. There are 18 front rows with 39 seats in each row, and 27 back rows with 4 seats in each row. If 5/6 of all the front row seats and 7/9 of the back row seats are sold, how much is the total ticket sales? Hey

Answer 1

5/6 of 18 is 15 so 3 left.
7/9 of 27 is 21 so 6 left.
total 9 left.

Answer 2

so first you do 18*39 to get 702
and 27*4 to get 108
then do 702* 5/6 to get 585
and 108*7/9 to get 84
then add 585+84 to get 669 tickets sold
