What is a ratio of 2 integers where the denominator is not equal to 0?
It is a rational fraction.
Why can't the denominator of the rational number A over B equal 0.?
Because division by 0 is not defined.
Is twenty over nineteen a rational number?
Yes. A rational number can be written as a simple fraction where the numerator and denominator are integers, given that the denominator does not equal 0.
What is it called when you have to set the denominator equal to 0 so you can find what the soultion can not be?
you are finding values to be excluded from the domain.
What are algebraic fractions?
Algebra is the study of unknown factors (known as variables). Algebraic fractions are fractions with variables in the numerator or denominator, such as 36/x. Others include x2/y or 5x/y3. Since division by 0 is impossible, variables in the denominator have certain restrictions. The denominator can never equal 0. Therefore, in the fractions 36/x . . . x cannot equal 0 x2/y . . . .y cannot equal 0 5x/y3 . . .y cannot equal 0 ---- [Edit] Yes. Also called rational expressions. An example: m + 7 ---------------------- (m - 6) (m + 2) so, m-6 cannot equal 0, this means that m cannot equal 6, and m + 2 cannot equal 0 also, this means that m cannot equal -2
