<span>tan(-180°) = y/x = 0/(-1) = 0</span>

The ratio would be 16:14 and then simplify it to 8:7
We can break down the number 6647 into:
6647=6000+600+40+7
The first 6 in the number is in the thousands place (6,000), and the second 6 is in the hundreds place (600).
The first 6 is 10 times greater than the second one.
