Question

Brandon mows his lawn once every 4 days. Thomas mows his lawn once every 3 days. Celena mows her lawn once every 6 days. If they are all mowing the lawn today, in how many days will they be mowing their lawns together again?

Answer 1

Answer: The Answer is 12

Step-by-step explanation: This is because each number's LCM (Least Common Multiple) is 12. Ex. 4,8,12 3,6,9,12 6,12

Answer 2

24 days

Explanation:

Given that;

Brandon mows his lawn once every 4 days, Thomas mows his lawn once every 3 days. Celena mows her lawn once every 6 days. Then assuming today is day 1,

Brandon will mows his lawn on the following dates

1,5,9,13,17,21,25,29 (adding 4 days)

Thomas will mows his lawn on the following dates

1,4,7,10,13,16,19,22,25,28 (adding 3 days)

Celena will mows her lawn on the following dates

1,7,13,19,25,31 (adding 6 days)

Comparing all the days, all 3 will mow their lawns on the 25th which is 24 days after the first day.
