Can pi be represented as a fraction of two rational numbers?
Pi can be expressed as the ratio π/1. It cannot be expressed as ratio of two integers (i.e. it is not rational). Being expressible as a ratio of integers has nothing to do with technology.
Can pi be a fraction of integers?
Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction.
How can pi be written as a fraction?
The pi value in fraction is 22/7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations. ‘π’ is not equal to the ratio of any two number, which makes it an irrational number.
Can be expressed as a fraction of two integers?
The rational numbers are the set of numbers that can be written as a ratio of two integers. In other words, any number that can be written as a fraction where both the numerator and the denominator are integers is a rational number.
Is pi impossible to write a fraction?
Answer: Pi cannot be expressed as a fraction as it is an irrational number. Explanation: In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find the area of a circle by multiplying the radius squared times pi.
Is pi an integer?
Pi is an irrational number. Irrational numbers are the real numbers that cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q≠0. Pi (π) is an irrational number because it is non-terminating.

How did Archimedes find pi?
Archimedes’ method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the perimeter of a polygon circumscribed outside a circle (which is greater than the circumference).
How do we know pi is infinite?
Pi is finite, whereas its expression is infinite. Pi has a finite value between 3 and 4, precisely, more than 3.1, then 3.15 and so on. Hence, pi is a real number, but since it is irrational, its decimal representation is endless, so we call it infinite.
Can pi be expressed as a fraction using whole number?
Irrationality and normality
π is an irrational number, meaning that it cannot be written as the ratio of two integers. Fractions such as 22/7 and 355/113 are commonly used to approximate π, but no common fraction (ratio of whole numbers) can be its exact value.
How did aryabhatta calculate pi?
Aryabhata discovered an approximation of pi, 62832/20000 = 3.1416. He also correctly believed that the planets and the Moon shine by reflected sunlight and that the motion of the stars is due to Earth’s rotation.
How long has pi been studied by humans?
Pi (π) has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated π to that number of places, we would still only be approximating its actual value. Here’s a brief history of finding π.
Who memorized the most digits of pi?
Twenty-five-year-old Rajveer Meena, a native of Morchala village of Sawaimadhopur district in Rajasthan on Saturday was able to memorise 70,000 digits of the mathematical value of Pi.
What is the 1000000 digits of pi?

What value did the Chinese give pi?
Zu Chongzhi, a Chinese mathematician and astronomer from the 5th century, had made a remarkable achievement by determining the Pi value with an accuracy of seven decimal places, between 3.1415926 and 3.1415927. His calculation remained the world’s most accurate for nearly 1,000 years until the 14th century.
Who invented 0?
Brahmagupta
“Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets. He developed a symbol for zero: a dot underneath numbers.
Why is pi called pi?
It was first called “pi” in 1706 by [the Welsh mathematician] William Jones, because pi is the first letter in the Greek word perimitros, which means “perimeter.”
Who invented math?

Who discovered the symbol Infinity ∞ *?
mathematician John Wallis
The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655. Three main types of infinity may be distinguished: the mathematical, the physical, and the metaphysical.
