Gary has guitar lessons every 5 days and band practice
every 4 days. his first band practice is in 4 days and his
first guitar lesson is in 5 days. in 100 days, how many
times will gary have had guitar lessons and band
practice on the same day? explain how you know.

He will have guitar lessons and band practice at the same day 5 times.

Step-by-step explanation:

Hi, to answer this question we have to find the least common multiple (LCM) of both numbers:

5 : 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100

4: 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96,100

So, the LCM is 20, it means that every 20 days he will have practice and lessons the same day.

If we divide 100 /200 = 5  

He will have guitar lessons and band practice at the same day 5 times.

Feel free to ask for more if needed or if you did not understand something.
