7.968 - 0.002 = 7.966
2 thousandths = 2 / 1000 = 0.002, so 6.667 - 0.002 = 6.665
2/1000 = .002 2.779 - .002 = 2.777

The variation in the size of carrots - from less than 2 inches to well over 8 inches - is several orders of magnitude greater than the unit that you want to measure them in. As a result, any measure in that unit will have little, if any, meaning.
2 thousandths = 2 / 1000 = 0.002, so 6.667 - 0.002 = 6.665
2/1000 = .002 2.779 - .002 = 2.777
Less: 2+8/1000 v. 2+8/10

The thousandths digit is the third digit after the decimal point; use the next digit to the right (the fourth digit after the decimal point) to decide whether to round up (if it is greater than or equal to 5) or round down (if it is less than 5)). The next digit after the thousandths digit is 2 which is less than 5, so round down. Thus 5.45722 → 5.457 when rounded to the nearest thousandth.

Look at the digist in the ten-thousandths place. If it is 5 or greater, round the digist in thousandths place to the next higher number. If it is less than five, leave the digit in thousandths place as it is. In the case of 7.8298, rounding it to thousandths means the 9 will be a 0 and the 2 in hundredths place would change to a 3. It will be 7.830.
