hundred thousandths = 1/100,000 → 4 and 21 hundred thousandths = 4 21/100000 = 4.00021
Twenty-one hundredths.
21/125
0.021
105/441 = 5/21
You would write it like this 21 or 2.1*10^1.
2.0*1021 is already in standard form!
It is 8.021
15,021,000
20,000,000,000,000,000,000,000
hundred thousandths = 1/100,000 → 4 and 21 hundred thousandths = 4 21/100000 = 4.00021
It is already in standard form.
You would write it like this 21,000,000 or 2.1*10^6.Another Answer:-It is the same as in scientific notation and it is: 2.1*10^7
It is already in standard form.
