The identity property
What do you multiply by to get identically what you started with? Multiply by 1. a x 1 = a
The multiplicative inverse property states that if you multiply a number by its reciprocal the total will equal one. A x 1/A = 1
In multiplication, when you multiply a number by 1, and you have the same number, that's called the identity property of one.
The property that allows you to multiply a number by 1 and have the product equal to the original number is called the Multiplicative Identity Property. This property states that for any real number ( a ), the equation ( a \times 1 = a ) holds true. It highlights the unique role of the number 1 in multiplication, where it does not change the value of the original number.
when you multiply -1 to a fraction it makes the fraction negative 7 -7 -- x -1= --- 8 8

In multiplication, when you multiply a number by 1, and you have the same number, that's called the identity property of one.
A reciprocal is the number you have to multiply a given number by to get 1. Ex) you have to multiply 2 by 1/2 to get 1. therefore the reciprocal of 2 is 1/2 As implied above, a property of two reciprocals is that their product equals 1. Another name for "reciprocal" is "multiplicative inverse."
Basically, this property dictates that no matter what you multiply by 1, it retains it's "identity". Example: 72 x 1 = 72. In math, if something is always the case, it is a Property.

The multiplicative property of equality. Multiply each side by -1/3.
Distributive Property
distributuve property
Whether or not the distributive property can or should be used depends on what you wish to multiply 43.2 by. For example, if you wish to multiply 43.2 by 10, the distributive property is irrelevant!
