## Are pi and 22 7 the same?

The simplest approximation for Pi is just 3. In the past, many math books listed Pi as 22/7. Again, this is just an approximation but it is better than the value of 3 (actually 22/7 is closer to Pi than just writing 3.14). The early history of mathematics covers many approximations of the value of Pi.

### Is 22 7 A rational number or irrational number?

All rational numbers can be expressed as a fraction whose denominator is non-zero. Here, the given number, 22⁄7 is a fraction of two integers and has recurring decimal value (3.142857). Hence, it is a rational number.

#### What is the exact value of 22 by 7?

The approximate value of 22/7 is 3.14285714. Keep in mind 22/7 is only used as π for convenience. The value of 22/7 is equal to 3.142857…….. This value is approximately equal to value of pi, that is 3.1416.

**Is 22 7 repeating or terminating?**

227 is a fraction which is very close to π . However, 227 is a rational number which can be written as a recurring decimal .

**Why is 22 7 so close to pi?**

The Pi’s fractional value is 22/7. Since pi is an irrational number i.e digits after decimal point are never ending and is non terminating i.e 3.1415926 … and so on. That is why 22/7 is used for calculations.

## Why is 22 7 an irrational number give reason?

22/7 is a rational number. All rational numbers can be expressed as a fraction whose denominator is non zero. Whereas, pi cannot be expressed in the fraction of two integers and has no accurate decimal value, so pi is an irrational number.

### Which of the following is not a rational number 22 7?

22/7 is irrational number. 0.120120012000……. is irrational number.

#### Will pi ever end?

Technically no, though no one has ever been able to find a true end to the number. It’s actually considered an “irrational” number, because it keeps going in a way that we can’t quite calculate. Pi dates back to 250 BCE by a Greek mathematician Archimedes, who used polygons to determine the circumference.

**What is the meaning of 22 7?**

What is the value of pi? The value of pi is approximately 3.14, or 22/7. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers.

**Is 987 10500 a terminating decimal?**

987 / 10500 = 47 / 500. 2 and 5 are the factors. If a fraction contains no other prime factors other than 2 and 5, it can be written in the lowest terms as the terminating decimal. Therefore, 987/10500 is terminating decimal.

## How was pi discovered?

The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. In this way, Archimedes showed that π is between 3 1/7 and 3 10/71.
