Question

Tom and David get their haircut at the barber shop on Saturdays Tom gets his haircut every four weeks David gets his haircut every six weeks one Saturday Tom and Dave got their haircut at the same time when will Tom and David get their haircut the same day again

Answer 1

Step-by-step explanation:

Think of it as a ratio problem.

Tom gets his haircut every 4 weeks and David gets his haircut every 6 weeks. So you can write it as 4:6.

The easiest way that I know of to do this is to find multiples.

4: 4x2=8 4x3=12

6: 6x2=12

So the twelfth week they will get their haircuts the same day.
