What is 160,656 round to the nearest hundred thousand

We can round 160,656 to 200,000.
Because 160,656 is more nearest to 200,000 than 100,000, a the second digit after 1 is 6 which is greater than 5 and close to 10 than 1. if it is less than 5, for example if the number is 140,656 then the number will be rounded to 100,000 as that one is more closest than 200,000.
But here 160,656 is rounded to 200,000.

Iwould say they are complementary because that’s the division of a 90 degree angle and it’s split between the middle of them
