What is the difference between a rational number that is not an integer and a rational number that is an integer?
When expressed as a ratio of two integers (not intergers!), the simplest form for the integer but not others, has 1 as the denominator.
What is a ratio of 2 integers where the denominator equals 0?
A ratio with denominator 0 is not defined.
What kind of number that cannot be written with an integer numerator and nonzero integer denominator called in math?
This kind of number is called "irrational", meaning (to a mathematician!) "not a ratio."
How can the terms of a ratio be used to write a equivalent ratio?
Multiply both the numerator (top) and the denominator (bottom) of the fraction by any non-zero integer. You will have an equivalent fraction.
Can the denominator be an integer in a rational number?
A rational number is defined as a number that can be expressed as the ratio(fraction) of two integers.So if you see a fraction that you know is a rational number, and the denominator isn'tan integer, there's always something you can do to simplify it, without changing its value,so that the denominator and the numerator both areintegers.
