Answer 1

Answer:

He has 5 ways to arrange them in a array.

Step-by-step explanation:

colby has 16 jars of spices.He wants to arrange them in arrays.

An array is a systematic arrangement of similar objects, usually in rows and columns.

So, the choices he could have to form an array is the possible number of ways he can arrange them in rows and columns and in table it could be seen as:

S.no.                  Number of rows              Number of columns

1                                16                                           1

2                                8                                           2

3                                 4                                           4

4                                 2                                           8

5                                  1                                          16

Hence, the number if arrays he could use to arrange them is 5.

1x1's, etc

So, what multiplies into 16?

8*2
2*8

So, he can either arrange them in any of these ways.
