There is no special name. Maintaining the proportion would be a description but it is not used as a name.
Dividing 4 and 5 by 2 gives 2 and 2.5 : so what?
Squaring for multiplying, and if you are dividing by the same number, you get 1
Multiplying and dividing are inverse operations; multiplying increases a quantity while dividing decreases it. Both processes involve the same numbers but yield different results based on the operation applied. For example, if you multiply a number by a factor, dividing that product by the same factor returns you to the original number. This relationship is fundamental in mathematics, illustrating how quantities can be scaled up or down.
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
it is the same as multiplying by 0.4
Dividing by twelve is the same thing as multiplying by 1/12. Thus, multiplying a number by 12/1, or twelve, is the opposite (inverse) of dividing a number by twelve.
There is no particular name for it. For example, the frequency and wavelength of electromagnetic rays are related, but multiplying them by the same number, or dividing, makes no sense.
Squaring for multiplying, and if you are dividing by the same number, you get 1
The answer is simplest form
Details about multiplying and dividing rational number involves modeling multiplying fractions by dividing squares to equal segments and then overlap the squares.
Because multiplying or dividing them by the same NON-ZERO number does not alter their ratio.
it is the same as multiplying by 0.4
No, taking ½ of a number is the same as dividing it by 2. Dividing a number by ½ is the same as multiplying it by 2.
Dividing by a non-zero rational number is the same as multiplying by its reciprocal.
The number of significant figures should be equal to the significant figures in the least precise measurement.
no, dividing a number is halving it, multiplying iy by 2 is doubling it
Dividing by twelve is the same thing as multiplying by 1/12. Thus, multiplying a number by 12/1, or twelve, is the opposite (inverse) of dividing a number by twelve.
This is related to the fact that dividing by a number is the same as multiplying with the number's reciprocal.
