It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.

It can be written in the form of the ratio 55555/100000.

Any, and every, irrational number will do.

zero is rational because it can be written as a fraction where the denominator is not equal to 0. it can be written as 0/1, 0/2, 0/3, etc

6.52 is a rational number because it can be expressed as a fraction in the form of 163/25 whereas irrational numbers can't be expressed as fractions.

No, 1/2 is rational, but not a whole number.

It is rational because it can be expressed as the ratio 400040004/10000000000.

It really depends what the equation looks like. For example, if the variable is added to other expressions, you can subtract the variable on both sides. Here is an example:3x + 3 = 2x + 10 If you subtract 2x from both sides, you'll end up having the variable only on one side.

Explanatory (or predictor) variable: A variable which is used in a relationship to explain or to predict changes in the values of another variable; the latter called the dependent variable.

It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.

To solve would be to rewrite the equation in terms of the variable in the equation. For example, solve: 3x-2=7. You would solve for the variable x; e.g. 3x=9 and x=3. To evaluate, you would be given an equation with a variable or variables. You would need to be given a value for the variable(s) to substitute into the equation. For example evaluate the equation for x=3; equation is x2+1. Substitute 3 in for x; or 32+1=10. To simplify, reduce the equation to its simplest form. This will involve operations such as: factoring, adding, subtracting, dividing, canceling terms, and so forth. For example simplify the equation: 3x3/9x2. The 3/9 is simplified to 1/3 and x3/x2 is simplified to x. So the original equation simplified is: 1/3 times x or (1/3)x or x/3.Which is the right answer for most of you who does not know.
