fraction word problem

Question

A federal law requires that all residential toilets sold in the United States use no more than 1_3/5 gallons of water per flush. Prior to this legislation, conventional toilets used 3_2/5 gallons of water per flush. Find the amount of water saved in one year by a family flushing the toilet 22 times each day if one conventional toilet is replaced with a new low flow one. (1 year = 365 days)

Answer 1

3 2/5 = 17/5

1 3/5 = 8/5

 

17/5 - 8/5 = 9/5

 

365(22)(9/5) = 14,454 gallons
