Bumblebee · Answer 1

In 12 weeks they will get their hair cut again on the same day.

Step-by-step explanation:

Tom gets his hair cut every 4 weeks. David gets his hair cut every 6 weeks.

One Saturday, Tom and David got their hair cut at the same time.

To solve this we will find the LCM of 4 and 6.

4 = 2 x 2

6 = 2 x 3

LCM = 2 x 2 x 3 = 12

So, in 12 weeks they will get their hair cut again on the same day.
