Doubling or halving.

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

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

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

It will give you a perfect square.

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

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

It is either two quantities that are larger or smaller than the ones that you started with, depending on whether the number that you multiplied or divided by was greater than or less than 1.Multiply by a number greater than 1 : both larger.Multiply by a number less than 1 : both smaller.Divide by a number greater than 1 : both smaller.Divide by a number less than 1 : both larger.

Re-scaling or (for selected vales of the same number) normalising.

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.

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.

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.

Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places

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

every number does that

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

The inverse or opposite of the operation of multiply is divide. So the inverse operation of multiply by 24 would be to divide by 24 or multiply by the inverse of the number (1/24).

A multiple of a number is any number which can divide evenly by the original number. It is called a multiple because you can multiply the original number to arrive at it. For example, 14 is a multiple of 7, because 14 can divide by 7. It is called a multiple because I can do 7x2 to get to 14.

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

one fourth: divide the number by 4, or multiply it by 0.25half: divide the number by 2, or multiply it by 0.5 three fourths: multiply the answer to the first by 3, or multiply the original number by 0.75

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

The number you divide into is called the divisor.
