How do you write one thousand twelve hundred?

Answer 1

You cannot have such a number as one thousand twelve hundred, as these two components would interfere with place values. One thousand would be written 1000, while twelve hundred would be written 1200.

Answer 2

To write one thousand twelve hundred, you would write it as "1,200." This is because one thousand is represented by the number 1 followed by three zeros, and twelve hundred is represented by the number 1 followed by two zeros. Combining the two, you get 1,200.
