Prove that if x is irrational, then 1/x is irrational

ozzi

Proof by contradiction.

Let assume that when $x$ is an irrational number, then $\dfrac{1}{x}$ is a rational number.

If $\dfrac{1}{x}$ is a rational number, then it can be expressed as a fraction $\dfrac{a}{b}$ where $a,b\in\mathbb{Z}$ .

$\dfrac{1}{x}=\dfrac{a}{b} \Rightarrow x=\dfrac{b}{a}$

Since $a,b\in\mathbb{Z}$ , the number $x=\dfrac{b}{a}$ is also a rational number. But this contardicts our initial assumption that $x$ is an irrational number. Therefore $\dfrac{1}{x}$ must be an irrational number.

1/6 also is 2/12. So, there is 9/12 of the pasta left.

Sal and Jen went to the store together, and each bought the same car stereo.

scZoUnD [109]

Answer: Sal used a debit card and paid a total of $324.80 for the stereo. (I took the test too)

Step-by-step explanation: Multiply $21.30 by 18 months. Then subtract the interest, $58.60, from the product because Sal paid immediately with a card which implies using a debit card. You get $324.80.
