Question

what property is illustrated by the statement 1×y=y? A. MULTIPLICATIVE IDENTY B. COMMUTATIVE C. ASSOCIATIVE PROPERTY OF MULTIPILICATION D. MULTIPLICATIVE PROPERTY OF ZERO

Answer 1

The appropriate choice is ...

... A. MULTIPLICATIVE IDENTY

_____

y retains its identity when it is multiplied by 1. (It becomes something else when multiplied by anything other than 1.)

Answer 2

This has nothing to do with zero. It is not mentioned at all. If y = 0 then D would apply, but no such restriction is present. The answer is not D

There has to be 3 numbers multiplied together to use the associative properties of multiplication as in (2 * 3) * 5 = 2 * (3 * 5) . The order that we multiply does not matter.

The commutative property could be true, and it is you second best answer (believe it or not) but, 1 * y = y * 1 is kind of trivial. So don't pick B until we find out about A

This often shows up 1 * x is the same thing as x. This is called the multiplicative identity.

A. <<<< Answer.
