Question

Which property of real numbers should be used to rewrite the numerical expression 100 (84 + 63) as 100(84) + 100 (63)?distributive property of multiplication over additioncommutative property of additionassociative property of additionidentity property of addition

Answer 1

Write out the expression given

`100(84+63)`

Consider the equation below

`a(b+c)=ab+ac`

In the equation above, the term "a" outside the paranthesis is distributed over the the terms in the paranthesis,

Henece, we say a distribute over b and c

Therefore,

to write the numerical expression

`100(84+63)`

As

`100(84)+100(63)`

We apply the

Distributive Property of Multiplication Over Addition
