Jack has baseball practice every third and swimming practice every second day. During a month that has 30 days how many days will jack have both practices.
I am a little stuck on this one.
Can you point me in the right direction?
6
So you would do 3x2=6
Then 30/6=5
ng,k,,
4
Of course! To find out how many days Jack will have both baseball and swimming practices, we need to determine the common multiples of 2 and 3 within a month that has 30 days.
To start, let's list the days:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30
Now, we can mark the days where Jack has baseball practice every third day by placing a "B" next to them:
1, 2, B, 4, 5, B, 7, 8, B, 10, 11, B, 13, 14, B, 16, 17, B, 19, 20, B, 22, 23, B, 25, 26, B, 28, 29, B
Similarly, we mark the days where Jack has swimming practice every second day by placing an "S" next to them:
1, S, B, S, 5, B, S, B, S, 11, B, S, 13, 14, S, B, S, B, 19, S, B, S, 23, B, S, 25, S, B, S, 29, B
Now we can see that there are 10 days where both a "B" and an "S" are marked next to them. Therefore, in a month that has 30 days, Jack will have both baseball and swimming practice for 10 days.
