Answer:

All properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse 3. multiplicative identity

What is commutative property of addition?

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have: x + y = y + x

Thus, if we take 3 numbers as a,b and c;

a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a

We have been given an expression;

2/7 • 53 • 7/2

53 • 2/7 • 7/2

53 • 1

53

Then all properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse

3. multiplicative identity
