To find the multiplication fact using the arrays for 2x9 and 5x9, we need to understand how arrays work.
An array is a visual representation of multiplication where rows and columns are used to organize the numbers being multiplied. In this case, we have two arrays: one for 2x9 and another for 5x9.
For the array representing 2x9, we have 2 rows and 9 columns, like this:
| | | | | | | | | |
| | | | | | | | | |
For the array representing 5x9, we have 5 rows and 9 columns:
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
To find the multiplication fact, we count the total number of squares in the combined arrays. Since we have 2 rows of 9 squares in the first array and 5 rows of 9 squares in the second array, we can add the number of squares together:
2x9 + 5x9 = (2 + 5) x 9 = 7 x 9
Therefore, the multiplication fact we can find by using the arrays for 2x9 and 5x9 is 7x9, which is equal to 63.
