Answer 2

To solve this expression, you need to perform the operations in the correct order: multiplication and division before addition and subtraction. Let's break it down step by step:

1. 640 divided by 2400 equals 0.26666667.
2. 4850 divided by 5120 equals approximately 0.94921875.
3. 4900 divided by 6240 divided by 2140 equals approximately 0.00036587592.
4. 4720 divided by 4330 equals approximately 1.08843997.
5. Now, we can multiply all these results together:

0.26666667 * 0.94921875 * 0.00036587592 * 1.08843997 * 7103 * (3720 divided by 4).

6. Calculate the result of the multiplication:

0.26666667 * 0.94921875 * 0.00036587592 * 1.08843997 * 7103 * (3720 / 4) ≈ 111.305295.

So, the final result is approximately 111.305295.
