Answer:
Commutative property of addition of rational numbers: Two rational numbers can be added in any order. Thus for any two rational numbers a/b and c/d, we have. (a/b + c/d) = (c/d + a/b)
First method:
What we can do first is to distribute directly 4.2 to 6 and
0.43, that is:
4.2 (6 + 0.43)
= 4.2 * 6 + 4.2 * 0.43
= 25.2 + 1.806
= 27.006
Second method:
We can add the two numbers 6 and 0.43 then multiply with
4.2, that is:
4.2 (6 + 0.43)
= 4.2 (6.43)
= 27.006
What we see is the Distributive Property of multiplication
which states that multiplying the sum of a number is similar to multiplying
each number and then adding the products.
I think it's the 0.0011098779
