No restrictions are required.
What is the greatest denominator for 4 and 19?
There can be no greatest denominator. Suppose x is the greatest denominator of two numbers a and b. That is to say, x is a multiple of a, x is a multiple of b and x is the greatest such number. Now consider the number 2x. It is a multiple of a, it is a multiple of b and it is greater than x. This contradicts the statement that x is the greatest such number. So such an x cannot exist.
Why can't you substitute 0 for a variable in an expression?
Sure you can substitute that. You just have to be careful to avoid division by zero - but the same may happen with other numbers as well. For example:If you have a denominator "x", then you can't substitute "x" by zero.If you have a denominator "x - 1", then you can't substitute "x" by 1, because if you do, the denominator will be zero.
The numerator and the denominator of a fraction have the same value?
The Answer:If both the denominator and the numerator is the same, it is equivalent to x/x = 1, which is the same concept x0 revolves upon.
