To estimate the value of π (pi) using the fraction 22/7, you can divide 22 by 7 in decimal form. When you perform the division, you get approximately 3.142857142857143.
So, the estimated value of π using the fraction 22/7 is 3.142857142857143.
However, it's important to note that π is an irrational number, which means it cannot be exactly expressed as a simple fraction or a finite decimal. Its decimal representation goes on indefinitely without repeating. The fraction 22/7 is just an approximation of π, but it is commonly used because it gives a reasonably accurate result for many mathematical and engineering calculations.
