90% = 0.900 to the nearest thousandth.
The first numeral after the decimal place is tenths. The second is hundredths, and the third is thousandths. 0.18 is already rounded up to the nearest thousandth; you can't round it up because there is no ten thousandths to round it up from. Sorry; this is a little confusing.
pi = 3.1415926535897932384626433832795... pi to the tenths = 3.1 pi to the hundredths = 3.14 pi to the thousandths = 3.142 pi to the ten-thousandths = 3.1416 pi to the 10th decimal places = 3.1415926536 etc. ============================
Digits to the right of the decimal point represent, in order from the point: tenths; hundredths; thousandths; ten-thousandths; hundred-thousandths etc etc. You want your figure rounded to 4 digits and normal practice is to round 5 upwards so the answer would be 0.7188
1 foot = 12 inches 1.67 feet = 1.67 x 12 = 20.04 inches.
The thousandths digit is 3. Since 2 < 5, then 0.2032 ≈ 0.203
It is 2000 + 30 + 2 and in base ten, that is 2032.
