3.14
pi is irrational so there can be no fraction that is equivalent. 22/7 is often used as a simple approximation.
22/7
3.14 is an approximation of the number pi. The number pi is also often approximated by the fraction 22/7.
they use simple machines for everything and every where.
Pi is an irrational number, meaning that it cannot be written as the ratio of two integers (fractions such as 22/7 are commonly used to approximate pi; no common fraction (ratio of whole numbers) can be its exact value).

the fraction 22/7 is often used as an approximation for the value of pi. it is off from the actual value by about 0.04 percent (1 in 2500). This would be like measuring a football field and being off by about 1.5 inches on your measurement. The fraction 355/113 is amazingly close, better than 1 part in 10 million
