(2 x 9) + (3 x 9) = 5 x 9 = 45 The GCF is 9.
Using my knowledge of greatest common factors and the distributive property, I can tell that 45 + 63 is equal to 9(5 + 7) or 9 x 12, which is 108. Of course, I could also tell that from my knowledge of addition.
45 + 30 (GCF = 15) = 15*3 + 15*2 = 15(3 + 2)
9(2 + 3) = (9 x 2) + (9 x 3) = 9 x 5 = 45
(4 x 6) + (5 x 6) = 9 x 6 = 54
(40+200)+(5+80)
95
The "distributive property" involves multiplication and addition, and there must be at least three numbers involved.
9(4+5)
45*60 can be written as (40+5)*60 and the distributive propoerty used to evaluate it. However, the associative property is much better 45*60 = 45*(2*30) = (45*2)*30 = 90*30 = 2700
(8x40)+(8x5)
9(4 + 5)
678 x 45 = 30510.
678 multiplied by 45 is 30,510
The product is 30,510
280 x 45 = (280 x 40) + (280 x 5)
