12 hundreds 9 thousands is

Equal, lesser than, greater than 129000.

1200 + 9000 = 10200

so, what do you think?

unless you meant

1209 thousands = 1,209,000

Well, let's see. 12 hundreds is equal to 1200, and 9 thousands is equal to 9000. So, if we add these two numbers together, we get 1200 + 9000 = 10,200. Therefore, 12 hundreds and 9 thousands is actually greater than 129,000. It's quite a bit bigger! Looks like we have ourselves a winner!

To determine if 12 hundreds 9 thousands is equal to, lesser than, or greater than 129000, you need to convert both values to the same units.

12 hundreds is equal to 12 * 100 = 1200.
9 thousands is equal to 9 * 1000 = 9000.

Adding these two values together gives us: 1200 + 9000 = 10200.

Now let's compare 10200 with 129000:

10200 is lesser than 129000.

To determine if 12 hundreds 9 thousands is equal to, lesser than, or greater than 129,000, we need to convert both numbers to the same unit.

12 hundreds can be written as 12 * 100 = 1,200.
Similarly, 9 thousands can be written as 9 * 1,000 = 9,000.

Now we have both numbers in the form of a thousands unit:
1,200 is equal to 1.2 thousands (because 1,200 divided by 1,000 equals 1.2).
9,000 is equal to 9 thousands.

Considering both in the thousands unit, we can compare them:
1.2 thousands is clearly lesser than 9 thousands.

Therefore, 12 hundreds 9 thousands is lesser than 129,000.
