WHAT MULTIPLICATION FACT CAN BE FOUND BY USING THE ARRAYS FOR 2X9 AND 5X9?
A 2 x 9 array can be multiplied by a 9 x 5 array, and will result in a 2 x 5 array.
I am talking about matrix multiplication, but that may not be what your question is about.
what multiplication fact can be found by using the arrays for 2x9 and 5x9?
To find the multiplication fact that can be found by using the arrays for 2x9 and 5x9, we first need to understand what these arrays represent.
An array is a rectangular arrangement of objects or numbers in rows and columns. In the case of multiplication, it is often used to represent the factors and the product.
Let's start with 2x9. This means we have 2 rows and 9 columns in our array. Each cell in the array represents the multiplication of the row number and the column number. So, in this case, the array for 2x9 would look like:
| 1 2 3 4 5 6 7 8 9 |
| 2 4 6 8 10 12 14 16 18 |
Each number in the array represents the product of the row number and the column number. For example, the number in the first row and the third column is 3, which is the product of 1 (first row) and 3 (third column). The number in the second row and the fifth column is 10, which is the product of 2 (second row) and 5 (fifth column).
Similarly, for 5x9, we would have 5 rows and 9 columns in our array. The array would look like this:
| 1 2 3 4 5 6 7 8 9 |
| 2 4 6 8 10 12 14 16 18 |
| 3 6 9 12 15 18 21 24 27 |
| 4 8 12 16 20 24 28 32 36 |
| 5 10 15 20 25 30 35 40 45 |
Now, let's find the multiplication fact common to both arrays. Look for the numbers that appear in both arrays. In this case, we can see that the number 18 appears in both arrays. This means that the multiplication fact we can find by using the arrays for 2x9 and 5x9 is 18.
So, the answer to your question is that the multiplication fact that can be found by using the arrays for 2x9 and 5x9 is 18.
