Juanita runs every third day and swims every fifth day. If Juanita runs and swims today, in how many days will she run and swim

Ber [7]

we know that

The least
common multiple (LCM) of two or more numbers is the least

number, other than zero, that is a multiple of all the numbers.

In this problem, we are looking for the least common multiple of $3$ and $5$

Multiply $3$ by $5$

$LCM=3*5\\ LCM=15$

therefore

On the $15th$ day after today, she will do both on the same day
