1. 6 (378) = 2268 = (189 + 189)6

Properties are:
Addition, you can have 6 + 107 = 113 
Commutative Property by moving: 107 + 6 = 113 
Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 
Distributive Property by allotting: 2 (3) + 107 = 113 

Multiplication, you can have 6 x 107 = 642 
Commutative Property by moving: 107 x 6 = 642 
Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 
Distributive Property by allotting: 2(3) x 107 = 642

A frame is 6in tall and 8 in wide. What if it was reduced to a width of 4in then how tall will it be

Answer:

3 in

Step-by-step explanation:

Apparently, we are to assume that the height and width are proportional:

height/width = (6 in)/(8 in) = (new height)/(4 in)

Multiplying by 4 in will tell us the new height:

new height = (4 in)(6/8) = 3 in

The reduced frame will be 3 inches tall.
