Answer 1

Answer:

(Rows, chairs)= (2,15), (3,10), (5,6)

Step-by-step explanation:

Given: There are 30 chairs in the band room.

Criteria: There has to be same number of chairs in each row. There must be more than one row and the number of chairs in each row must also be greater than the number of rows.

First finding the divisor of 30:

1,2,3,5,6,10,15,30

Now, we need to look into divisor which qualify the criteria in the multiple of rows and number of chairs.

∴ 30= $2\times 15$

  30= $3\times 10$

  30= $5\times 6$

∴ Mr Avery can use either of these option to arrange rows and chairs.

(Rows, chairs)= (2,15), (3,10), (5,6)
