Question

compare py and 22/7​

Answer 1

Pi is an irrational number---you can't write it down as a non-infinite decimal. This means you need an approximate value for Pi. The simplest approximation for Pi is just 3. ... 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).

Answer 2

Answer:

22/7 is a rational approximation to pi, just as 3.14 is. That is, both 22/7 and 3.14 are rational numbers (fraction and terminating decimal, respectively) that are close enough to the exact value of pi for elementary work. 22/7 is a rational number, namely 3.1428571428571428571428571428571...
