Question

every 1/2 hour Naomi stretches her neck; every 1/3 hour she stretches her legs; and every 1/6 hour she stretches her arms. Which parts of her body will Naomi stretch when 2/3 of an hour has passed?

Answer 1

Naomi will stretch each part if her body listed because 1/2 is less than 2/3. She will have stretched her neck once; 1/3 is less than 2/3. 1/3 + 1/3 is 2/3 so she would have stretched her arms twice; 1/6 is less than 2/3 and goes into 2/3 4 times so she would have stretched her legs 4 times. Hope I helped!
