$π = 3.142$ $pi=3.142$

$π$ $pi$ is roughly $3.142$ $3.142$

Writing that as a fraction, we get $\frac{3142}{1000}$ $3142/1000$ which subsequently gives $\frac{22}{7} \approx 3.142$ $22/7~~3.142$

They are not equal, but their values are very close.

$π \neq \frac{22}{7}, π \approx \frac{22}{7}$ $pi != 22/7, " "pi ~~ 22/7$

$\frac{22}{7} and π$ $22/7 and pi$ are not equal, but we can say that

$π \approx \frac{22}{7}$ $pi ~~ 22/7" "$ they are approximately equal.

$π$ $pi$ is an irrational number - it is an infinite, non-recurring decimal.
Its value is $3.141592654..............$ There is NO pattern.

$22/7$ is a fraction which is very close to $pi$ .

However, $22/7$ is a rational number which can be written as a recurring decimal . $22/7 = 3.142857bar142857...$ There IS a pattern.

If $pi and 22/7$ were equal, their difference would be $0$

However: $22/7 - pi = 0.00126448925...$

Therefore they are not equal, but,

$22/7 = 3 1/7$ is very close to $pi$
