Here's another way to prove that 22/7 > pi:

consider the integral of
x^4 (1-x)^4/(1+x²)
from 0 to 1, which is clearly positive and can be solved by hand to be equal to 22/7-pi. So we get pi < 22/7.

22/7 to 5 decimal places is 3.14285
π to 5 decimal places is 3.14159

so 22/7 is greater.

There is no exact value for pi but this could be an approximatation:

3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 5923

On the other hand, 22/7 is approximately

3.142857142857142857, which is obviously greater than pi..

22/7 is greater than pi

Pi = 3.141592
22/7 = 3.1428

Both are equal since the value of pi and 22/7 is 3.14

π = 22/7 or 3.14
