distributive
6 x 4.3 = 6 x 4 + 6 x 0.3 = 24 + 1.8 = 25.8
(7 x 10) + (7 x 4) + (7 x 0.6) = 70 + 28 + 4.2 = 102.2
One way is: 15 * 104 = 15*(100 + 4) = 15*100 + 15*4 = 1500 + 60 = 1560
5 x 9 = (5 x 3) + (5 x 3) + (5 x 3)
distributive.

7*9 = 9*(10 - 3) = 90 - 27 = 63
You don't need to use the distributive property. 3*17 = 51 so 30*17 = 510 Why invoke procedures that are not necessary?
5*43 = 5*(40 + 3) = 5*40 + 5*3 = 200 + 15 = 215
7*46 = 7*(40 + 6) = 7*40 + 7*6 = 280 + 42 = 322
Some people use the distributive property to add 24 and 36, but you wouldn't use it to find the GCF which, by the way, is 12.
6 x 4.3 = 6 x 4 + 6 x 0.3 = 24 + 1.8 = 25.8

Assuming the operation is multiplication, 597 * 4 = (600 - 3)*4 = 600*4 - 3*4 = 2400 - 12 = 2388
(8x40)+(8x5)
(7 x 10) + (7 x 4) + (7 x 0.6) = 70 + 28 + 4.2 = 102.2
