Answer 2

To solve the expression:

((99999 * 55555) / (1 + 3 + 5 + 7 + 9 + 8 + 6 + 4 + 2)) / ((77777 * 44444) / (1 + 2 + 3 + 4 + 5 + 6 + 7))

Follow the order of operations, which is parentheses, then multiplication and division from left to right.

First, calculate the sums inside the parentheses:

1 + 3 + 5 + 7 + 9 + 8 + 6 + 4 + 2 = 45 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28

Now, we can substitute these sums back into the expression:

((99999 * 55555) / 45) / ((77777 * 44444) / 28)

Next, calculate the multiplications:

99999 * 55555 = 5555439445 77777 * 44444 = 3457401188

Now, substitute these results back into the expression:

(5555439445 / 45) / (3457401188 / 28)

Now, perform the divisions:

(5555439445 / 45) = 123454209 (3457401188 / 28) = 123450041

Finally, divide the results:

123454209 / 123450041 ≈ 0.999966727

So, the approximate value of the given expression is approximately 0.999966727.
