Oh, what a happy little question! When you have an array for 2 times 9, you can see 2 rows of 9, which equals 18. And when you have an array for 5 times 9, you can see 5 rows of 9, which equals 45. Keep exploring those arrays and you'll create a beautiful landscape of multiplication facts!
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
Some common multiplication strategies include the Latis Strategy, The Algebra Strategy, and the Stacking Strategy.
9
Using reciprocals, a/b divided by c/d is the same as a/b times d/c. If you multiply this, you get ad/bc.Without thinking about this as reciprocals, you can do this multiplication directly, cross-multiplication so to speak.
Approximately 790 (792).
7x9
3 times 9 and 7 times 9.
The multiplication fact (singular, not plural 'facts') that can be found is 7x9 = 63. Using the arrays, a 2x9 array (2 rows of 9 items) and 5x9 array (5 rows of 9 items) is 63: 2x9 = 18 5x9 = 45 18 + 45 = 63
9+9 and 9+9+9+9+9
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
Some common multiplication strategies include the Latis Strategy, The Algebra Strategy, and the Stacking Strategy.
10 x 5?
Using multiplication 40 times 45 = 1800
9
They both cannot be
3 times 35 equals 105
It is equivalent to multiplying by the cube of that number.
