In the barber shop there are two leaking taps. The first tap leaks a drop of water every 75 seconds and the second leaks a drop every 12 seconds. At 11.10 am both taps lost a drop of water at the same time. At what time will the two taps lose two drops of water again at the same time? Leonardo wants to cut two wooden strips

1.54 m and 2.42 m long respectively in pieces all having the same length that is as large as possible.

a. How many inches should each piece be long?

b. How many pieces will be obtained in all?
