distributive
(7 x 60) + (7 x 5) = 420 + 35 = 455
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
5 x 9 = (5 x 3) + (5 x 3) + (5 x 3)
distributive.
distributive
7*9 = 9*(10 - 3) = 90 - 27 = 63
(7 x 60) + (7 x 5) = 420 + 35 = 455
You don't need to use the distributive property. 3*17 = 51 so 30*17 = 510 Why invoke procedures that are not necessary?
Multiplication can be the first step when using the distributive property with subtraction. The distributive law of multiplication over subtraction is that the difference of the subtraction problem and then multiply, or multiply each individual products and then find the difference.
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
