What is difference between fractional and rational numbers?
All rational numbers are fractional but all fractional numbers are not rational. For example, pi/2 is fractional but not rational.
What is the product of 2 rational numbers?
It is a rational number.
How many rational numbers can be put between 2 and7?
There are an infinite number of rational numbers between any two rational numbers. And 2 and 7 are rational numbers. Here's an example. Take 2 and 7 and find the number halfway between them: (2 + 7)/2 = 9/2, which is rational. Then you can take 9/2 and 2 and find a rational number halfway: 2 + 9/2 = 13/2, then divide by 2 = 13/4. No matter how close the rational numbers become, you can add them together and divide by 2, and the new number will be rational, and be in between the other 2.
Are some integers not rational numbers?
All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.
Is the difference of any 2 rational numbers a rational number?
Yes it is. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
What can you say about the values of the ratios in the ratio table?
They represent rational numbers.
How do you turn an irrational number in to a rational number?
Some irrational numbers can be multiplied by another irrational number to yield a rational number - for example the square root of 2 is irrational but if you multiply it by itself, you get 2 - which is rational. Irrational roots of numbers can yield rational numbers if they are raised to the appropriate power
Can the product of any two irrational numbers be a rational number?
Yes. For example, if you multiply the square root of 2 (an irrational number) by itself, the answer is 2 (a rational number). The golden ratio (Phi, approx. 1.618) multiplied by (1/Phi) (both irrational numbers) equals 1 (rational). However, this is not necessarily true for all irrational numbers.
Are all rational numbers natural?
All of the natural numbers are rational, but there are still more rational numbers that aren't natural ones. Example: 1, 2, 3, 4, and 5 are all natural numbers, and they're all rational. 11/2, 21/2, 31/2, 41/2, and 51/2 are also rational, but they're not natural numbers.
What is the product of 2 rational numbers?
It is a rational number.

All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.
Are positive numbers rational numbers?
Not necessarily. +sqrt(2) is positive but not rational.
Is -1 1 2 rational number?
All whole numbers are rational numbers.
Is the difference of any 2 rational numbers a rational number?
Yes it is. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
What to numbers are multiplied together?
any 2 numbers can be multiplied together. eg. 2x1 is 2. 5x91000 is 455000
