Answer 1

Given:

Kim's array has 4 rows and 9 colums.

Rashida's array has 9 rows and 4 columns.

Let's determine the array that has more items.

To find the total number of items in an array, apply the formula:

Total number of items in an array = (number of rows) x (number of columns)

Now, using the formula above, let's find the number of items in each array.

• Number of items in Kim's array:

Number of items = 4 x 9 = 36

There are 36 items in Kim's array.

• Number of items in Rashida's array:

Number of items = 9 x 4 = 36

There are 36 items in Rashida's array.

Kim's array and Rashida's array have the same number of items.

Therefore, we can say both arrays have equal number of items.

ANSWER:

Both arrays have equal items.
