It might be called this because you are reducing something equally for someone or something else.
It requires division. You are dividing a pie between x number of friends.
Division would be the operation that would convert 15.5m to cm. You would divide by 100.
The inverse operation of addition would be subtraction. The inverse operation of subtraction would be addition. The inverse operation of multiplication is division and the inverse operation of division is multiplication. It is called the inverse operation because you are reversing the equation. If you add, subtract, multiply, or divide the same number on each side of the equation, then the equation would still be true. As long as you are doing the same thing on BOTH side of the equation. The reciprocal is used for dividing fractions. All you have to do for finding the reciprocal of a fraction is flip the fraction. Ex: The reciprocal of 1/4 is 4. The reciprocal of 5/8 is 8/5. You can check by multiplying the two fractions. It will equal to one if you did it right. I hope this helped a little bit.
The operation to get from 80 to 8 is division. Divide 80 by ten, and the answer is 8.
it is called IONIC compound
It's an operation. The factor would be the two numbers (or variables) you're adding, multiplying, etc.
Informally, many people would call the opposites. But the correct math term is inverse operations. Addition is the inverse operation of subtraction and multiplication if the inverse operation of division.
i think it would be a dictator

The word estimate is for a number, irrespective of the arithmetical operation involved. However, how you estimate for a number DOES depend on the operation. For example, if adding (or subtracting) 0.00496 form 123456, I would estimate 0.0049 as 0. But, it multiplying or dividing I would estimate it as 0.005 - it all depends on the context of the arithmetic operation.
