By this question, I presume the questioner means what is 2 + 453 ten thousandths. 453/10000 = 0.0453, so 2 - 453 ten thousandths = 2.0453
Fifty-one ten thousandths written in standard form is 0.0051
Fifty-one and eighty-three ten-thousandths can be written as 51.0083.
900.0250
7.0051 = seven and fifty-one ten-thousandths.
