If you mean 90 and 19/1000 then as a decimal it is 90.019
If you mean: 4 and 90/1000 then it is 4.09
90% = 0.900 to the nearest thousandth.
move the decimal point two places to the right - thus 90%
90% = 0.9
three and six hundred ninety-five thousandths
90 thousand = 90,000
In decimal form, 90% is .90. This is because when converting a decimal into a percent, you move the decimal point 2 places to the right, which is the same as multiplying that decimal by 100. You multiply it by 100 because you are converting that decimal into a fraction that will represent a percentage of a full 100%.
0.90 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 90/100 which simplifies to 9/10.
You can write 90 in short word form as ninety.
7 ones and 90 tenths written as a decimal is the same as 7 ones and 9 ones written as a decimal, so the answer is 16.0
decimal places go .1(tenths) .01(hundredths), and .001(thousandths) and there are 10 thousandths in a hundredth and 10 hundredths in a tenth .9 is 9 tenths which is 90 hundredths or 900 thousandths but normally you would just say "nine tenths"
In decimal form, we obtain: 9,000.0.
