# Are pi and 22 7 the same?

## 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.
