Answer 1

Answer:

multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.

Both sides were multiplied by 3 which still makes them equal

Answer 2

Answer:

The correct option is;

Multiplication Property of Equality

Step-by-step explanation:

The multiplication property of equality states that the product of both sides of an equation by a given number maintains the equality of the sides of the equation

For example, two containers hold the same volume of water, if the volume of water in each of the containers is doubled, they will still hold the same volume on each side.

For the given question, we have;

TR = UI then 3·RT = 3·UI

We have the same value of the multiplier on both sides of the equation therefore, the value of the result of the multiplication will also be the same on both sides of the equation.
