Which equation exemplifies the commutative property of multiplication? ? 1: 5+3=3+5 2: 7(5x2)=(7x5)2 3: 12x1=1x12 4: 4x4=2x8

3: 12x1=1x12

Step-by-step explanation:

An operation is said to be commutative if the answer to such mathematical operation remains the same no matter the way the variables are arranged. Commutative law is only true under operation addition and multiplication. For example, given two variables A and B, A and B are said to be commutative if

1. A+B = B + A (addition law)

2. AB = BA (multiplicative law)

Applying this to the question, the equation 12×1 = 1×12 exemplifies the commutative property of multiplication because the arrangements of the numbers does not affect the values to answers at both sides of the equation.

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
