There are 912 yellow chairs and blue chairs altogether in an auditorium. The blue chairs are arranged in 36 rows with 12 chairs in each row. The yellow chair are arranged in rows of 20. How man rows of yellow chairs are there?
First you have to do 36 times 12 which is 432, then subtract that from the total which is 480 then divide that by 20 and you get 24. Plz give this a thanks
