Question

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more than 20 rows. What are the possible number of rows that Brooke could set up?

Answer 1

You can divide 70 with 20. To get one possible answer

Answer 2

You need to find all of the factors of 70 and then not have any rows greater than 20.

Here are two examples, but I don't know if they makes any sense.

1 and 70 you can have 1 row of 70 chairs, but you can't have 70 rows of 1 chair
2 and 35 you can have 2 rows of 35 chairs, but not 35 rows of 2 chairs
3 is not a factor of 70
4 is not a factor of 70
5 you can do the rest yourself
