5(3+9) = 5x3 + 5x9 hope this helps
5x9.
5(5x2=10; 5x3=15; 5x9=45)
9/20 it is the simplest form. 45/100 = (5X9)/(5X20) =9/20
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
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
You can see that multiplication works both ways: 2x9=18 9x2=18 5x9=45 9x5=45 Arrays are also helpful in seeing the inverse relationship between multiplication and division.
As the product of its prime factors: 3*3*5 = 45
