Explanation:

Given are the number at the beginning of each strings.

We need to write multiples of number on first light of string on rest of lights on the string.

3:
`3* 1= 3 (given)`

`3* 2= 6\\3* 3= 9\\3* 4= 12\\3* 5= 15\\3* 6= 18\\3* 7= 21\\3* 8= 24`

7:
`7* 1= 7 (given)`

`7* 2= 14\\7* 3= 21\\7* 4= 28\\7* 5= 35\\7* 6= 42\\7* 7= 49\\7* 8= 56`

5:
`5* 1= 5 (given)`

`5* 2= 10\\5* 3= 15\\5* 4= 20\\5* 5= 25\\5* 6= 30\\5* 7= 35\\5* 8= 40`

9:
`9* 1= 9 (given)`

`9* 2= 18\\9* 3= 27\\9* 4= 36\\9* 5= 45\\9* 6= 54\\9* 7= 63\\9* 8= 72`

4:
`4* 1= 4 (given)`

`4* 2= 8\\4* 3= 12\\4* 4= 16\\4* 5= 20\\4* 6= 24\\4* 7= 28\\4* 8= 32`
