# Pi(e): A Dessert & A Number!

### This famous irrational number is approximately equal to 3.14159. Although this number is irrational, some of its multiples are actually __rational!__ Yeah, you read that right.

__According to the TI-84 Plus:__

## 8π = 25 + 553/4166 or 104,703/4166

## 15π = 47 + 823/6643 or 313,044/6643

## 35π = 109 + 907/949 or 104,348/949

## 36π = 113 + 179/1839 or 207,986/1839

## 37π = 116 + 642/2687 or 312,334/2687

#### (To the left of the OR's above are the fractions as mixed numbers; I like to use the plus sign between the integer & the fraction!)

In the image below are the digits of Pi up to 15 digits after the decimal point:

A very close rational number to **Pi** is **22/7** or **3 + 1/7**. If you subtract **Pi** from that number, you get a very small *rational* number!

## 22/7 - π = 6/4,745

Wacky, isn't it? Therefore:

## π + 6/4,745 = 22/7 or 3 + 1/7

### According to this Web page's theory, you can add, subtract, multiply or divide rational numbers & irrational numbers but get rational numbers as an answer!
