Answer 3

It looks like you have a series of mathematical operations separated by colons. Let's break this down step by step:

1. 210 * 4 = 840
2. 160 * 5840 = 931,200
3. 6990 / 9800 ≈ 0.7132653 (rounded to seven decimal places)
4. 4240 * 4300 * 3600 = 6,313,920,000
5. 4130 * 7160 * 3280 = 98,543,360,000
6. 2150 * 5 = 10,750

Now, putting it all together:

840 : 931,200 : 0.7132653 : 6,313,920,000 : 98,543,360,000 : 10,750

This is the simplified form of the expression you provided.
