Answer 2

They will exercise together on the 24th day again.

Given:

Jerwin exercises every 12 days

Nikki exercises every 8 days.

To find:

Number of days after which they will exercise again.

Solution:

LCM of 12 and 8 is required to find the number of days after which they will exercise again.

LCM stands for least common multiple. It is the smallest possible number which can be divided by two numbers.

Here, to find LCM of 12 and 8, first the factors of both the numbers are written as:

12= 2 x 2 x 3

8= 2 x 2 x 2

Now, taking the common numbers once and multiplying the rest i.e ,

LCM of 8 and 12 = 2 x 2 x 2 x 3 = 24

Hence, After 24 days Jerwin and Nikki will exercise together again.
