Problem: During the summer months, one ice cream truck visits Jeannette’s neighborhood every 4 days and another ice cream truck visits her neighborhood every 5 days. If both trucks visited today, when is the next time both trucks will visit on the same day?

Write all you working and explanation as a comment.

Then have a go at this?

20 days because the first one comes every 4 days and the second one comes every 5 days and LCM of 4 and 5 is 20 so the answer is 20 days

I think then next time both ice cream truck visit is in 20 days because the lowest common multiple of 5 and 4 is 20.

the next time the ice cream vans will come at the same day will be on day 20 because the van that comes every 4 day will come on day 4,8,12,16 and 20 and the ice cream van that comes every 5 days will come on day 5,10,15, and 20 as you can see there is a 20 on both of the dates

both trucks will visit on 2oth day beacuse 4 x 5 = 20 and 4 is the lowest common multiple 5 so 20 is the answer.

In the next twenty days,I know this because truck one comes every four days and truck two comes every five days,so truck one comes in four,eight,twelve,sixteen and twenty days.Truck two comes in five,ten,fifteen and twenty.

The answer is 20 because the first days they would be separate by 1 day, if I multiply 4 and 5 I get 20 and they are the lowest common multiples of 20.

I think both ice cream trucks would visit in twenty days because 20 is the lowest common multiple of 4 and 5. 4,8,12,16,20 and 5,10,15,20.
