You can multiply any pair of rational numbers as well as any irrational number and its reciprocal (or a rational multiple of its reciprocal. Thus pi * 3/7*(1/pi) is rational.

What kind of number do you get if you multiply two rational numbers?
You get a rational number.
What happens when you multiply rational numbers?
The product is a rational number.
What is the sum if you multiply two rational numbers?
Either way, you'll end up with a rational number, but you won't get a sum if you multiply.
Can you multiply three irrational numbers to get a rational number?
no
How are two or more rational numbers added together?
They make a rational number.
What kind of number do you get if you multiply two rational numbers?
You get a rational number.

Can you multiply three irrational numbers to get a rational number?
no
What happens when you add subtract multiply and divide rational numbers?
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
Which number can be multiplied to a rational number to explain that the product of two rational numbers is rational?
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.
How do you work out the prime factors of a number?
1. Find out which numbers multiply together to reach the target number, then find out which numbers multiply together to make the numbers that multiply together to reach the target number.
How are two or more rational numbers added together?
They make a rational number.
Are rational numbers closed under multiplication?
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
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
How do you find a rational number between two given rational numbers?
Add them together and divide by 2 will give one of the rational numbers between two given rational numbers.
Why rational number is also a real number?
Real numbers are defined as the set of rational numbers together with irrational numbers. So rationals are a subset of reals, by definition.
