Tracey has a stretching class every 4 weeks. Her sister has a karate class every 3 weeks. They meet at the recreation center this week for class. How many weeks will it be until they see each other again at the recreation center for class? __ weeks

Respuesta :

Answer:

The answer is: 12 weeks.

Step-by-step explanation:

To find out how many weeks it will be until Tracey and her sister meet again at the recreation center for class, we need to find the least common multiple (LCM) of the two numbers: 4 weeks (Tracey's stretching class interval) and 3 weeks (her sister's karate class interval).

The LCM of 4 and 3 is 12 weeks.

So, it will be 12 weeks until they see each other again at the recreation center for class.
