every 1/2 hour = 30 mins = stretches her neck
every 1/3 hour = 20 mins = stretches her legs
every 1/6 hour = 10 mins = stretches her arms
2/3 hour = 40 mins.
Naomi will stretches her legs and her arms at 40 mins of an hour.
In an hour, Naomi will stretch her neck two times, stretch her legs three times, and stretch her arms six times.

1/2 = 30 mins
1/3 = 20 mins
1/6 = 10 mins
2/3 = 40 mins
Now identify the times that are factors of 40
1, 40
2,
20
4,
10
5, 8
10 and 20 are the only corresponding times, therefore she will stretch her
legs and arms
after 2/3 of an hour has passed.
