Question

10. Use grids to draw all the possible arrays

Answer 1

Answer:

Please check the attached figure a to visualize the array grid for 5, 7 and 11.

Step-by-step explanation:

As the given number be 5, 7 and 11.

An array is basically the display of things in rows and columns. Students tend to draw arrays for multiples of a given number.

For example,  2 × 1 means the objects are placed in two rows and 1 column.

The numbers 5, 7 and 11 are prime numbers as they have only two factors  

• A prime number consists of just two factors, 1 and the number itself

• For example, 3 is prime number because the only factors of 3 are 1 and 3

So,  

As the factors of 5 are 1 and 5. Therefore, the possible number of drawing all the possible arrays of 5 will be two which are

• 1 × 5 and 5 × 1

As the factors of 7 are 1 and 7. Therefore, the possible number of drawing all the possible arrays of 7 will be two which are

• 1 × 7 and 7 × 1

As the factors of 11 are 1 and 11. Therefore, the possible number of drawing all the possible arrays of 11 will be two which are

• 1 × 11 and 11 × 1

Please check the attached figure a to visualize the array grids for 5, 7, and 11.
