Answer :

The answer to this question is there are 5 rows in 30 because 6x5=30 so it would be 5 ROWS. How you get that is you add 6 5 times and then you will get thirty if you do not know your multiplication that is another way of doing it.
[tex]6 * 5 = 30 or 5 * 6 = 30[/tex]There are 5 rows of 6 in 30 the way I got that was by counting by 6's 5 times
I hope this helped
