4 groups of 6 or 6 groups of 4:

Answer 2

If you have 4 rows of chairs and 6 columns then you have a total of 24 chairs this is because there are 6 groups of four chairs each. we can add these groups together my multiplying 6 times 4. In other words we add 6 to itself 4 times 6 + 6 + 6 + 6 = 24

hope this helps!

Answer 3

4 rows and 6 columns:

x x x x x x

x x x x x x

x x x x x x

x x x x x x

You could just count the x's in that diagram. But the easiest is to multiply 4 x 6 = 24.
