Answer 1

Answer:

She have both activities again on 20th day from now.

Step-by-step explanation:

Given :Ronna has volleyball practice every 4 days

         Ronna also has violin lessons every 10 days.

To Find : When will she have both activities again on the same day?

Solution:

We will find the LCM of 4 and 10

2  |   4 ,10

2  |   2 , 5

5  |   1  , 5

   |   1  ,  1

So, $LCM = 2\times 2 \times 5$

$LCM =20$

Hence she have both activities again on 20th day from now.
