7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
9
2/3 x 9/10 = (2x9)/(3x10) = 18/30 = 18÷6/30÷6 = 3/5
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 a product of its prime factors: 2*3*3 = 18
72 i guess!
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
18
There are no prime factors in that equation.
9
5x-2x=9
2x9=18
2/3 x 9/10 = (2x9)/(3x10) = 18/30 = 18÷6/30÷6 = 3/5
Special Education 2x9
2 times 3 to the second power equals to 2x9 or 18 2 to the second power times 3 equals to 4x3 or 12 therefore the least common factor is 2.
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
