Scaling is when you multiply or divide two quantities by the same number.

You multiply or divide the first quantity by the number and then you do the same for the other quantity.

Doubling or halving.

Squaring for multiplying, and if you are dividing by the same number, you get 1

If the quantities are related linearly, then the operation would mean SCALING Otherwise it is just operations on the two quantities by a constant

Yes, it is; except that the chosen number cannot be zero.

If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.

It is called algebra. When two quantities are related as long as you do the same operation to both (add, subtract, multiply, or divide) you do not change the relation

every number does that

If you have a number of square feet, divide it by 43,560 or multiply it by 0.00002296 to get the number of acres.If you have a number of acres, multiply it by 43,560 or divide it by 0.00002296 to get the number of square feet.

Multiply the number by 0.17. or Multiply it by 17 and then divide by 100.

You will end up with a positive number. With integers, if you multiply or divide an even amount of negative numbers, the answer will be positive and if you multiply or divide an odd amount, the answer will be negative.

The inequality sign changes direction. So 2<3 Multiply by -2 and you get -4>-6 (similarly with division).

Multiply the number by 2.5 and then divide by 100. Alternatively, multiply the number by 0.025

Multiply that number by 31 and divide by 100, or, simply, multiply that number by 0.31

it is when you multiply then divide then multiply the number you have got by 2

To change a number into a percentage multiply it by 100.

Multiply the denominator by the whole number, or divide the numerator by the whole number

If you multiply integers the results is an integer. If you divide integers (with one exception) the result is a rational number which, in some cases, may be an integer. However, the exception is that division by 0 is not defined.

Multiply or divide the number it precedes

You cannot just move the decimal when you multiply or divide by 101001000.

You get the number, divide by 100, multiply by 17

Any even number

-N/i=-Ni/(i*i) = (multiply top and bottom by i -Ni/-1 = Ni (i times i) = -1 You get a positive number (N) times i.

The size of the quantities involved doesn't matter. As long as you add or subtract (or divide or multiply) the same number to or from both sides of the equation, then the two sides remain equal.
