Step 1
Given,
Craig is training for a race.
He bikes every 2 days and swims every 3 days .
If he biked and swam today,
We have to find how many days will pass before he bikes and swims on the same day again.
Step 2
Number of days will pass before he bikes and swims on the same day again
= Least common multiple of 2 and 3
$$\displaystyle={2}\times{3}$$
Answer: $$\displaystyle={6}$$ days
