<u>are the rational numbers a subset of all real numbers?</u>
yes of course
by definition the real numbers is the union of the rational numbers and the irrational numbers
so we can say that the rational numbers are a subset
and every rational number is part of the real number
<u>are the rational numbers a subset of the irrational numbers?</u>
No
the rationals numbers are all those numbers that you can write as p/q with q different of 0, and the irrationals numbers are those that you cannot write as a fraction
so as you can see those are two completely different types of number, to be a subset every rational number must be in the irrationals , and by the definition we know it can't happen

To multiply a fraction, imagine it this way. Start with 1/4. Then if you multiply 1/4 by 2 it would be 1/2.
If you have a quarter, and you times that quarter by 2, you have half a dollar.
It only needs to be simplified if you can simplify the fraction.
