Mrs. Fisher has 91 watches at her store. She says she can put them into rows and columns without any watches leftover. Mr. Fisher says that she can only put them into one row. Who is correct, and why? (Working with prime and composites)

Respuesta :

This is a question of whether 91 is a prime number or not. And it is not so Mrs. Fisher is right, you can arrange them in 7 rows and 19 columns or vice versa. 7 and 9 are factors of 91.

Mrs. Fisher's claim is correct, and Mr. Fisher's claim is incorrect

The number of watches is given as:

[tex]n = 91[/tex]

91 can be expressed as the product of 7 and 13.

So, we have:

[tex]n = 7 \times 13[/tex]

This means that:

The 91 watches can be put in 7 rows and 13 columns or 7 columns and 13 rows.

Hence, Mrs. Fisher's claim is correct.
