What is distributive property?
The distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is
A(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
4 x 9.4
By using distributive property
= 4(9 + 0.4)
= 36 + 1.6
= 37.6
6.4 x 1.2
By using distributive property
= 6.4( 1 + 0.2)
= 6.4 + 1.28
= 7.68
3.5 x 4.9
By using distributive property
= 3.5( 4 + 0.9)
= 14.0 + 3.15
= 17.15
8.4 x 5.2
By using distributive property
= 8.4(5 + 0.2)
= 42 + 1.68
= 43.68
