In 3.68 remember
'3' is Units
'6' is Tenths
'8' is Hundredths
Remember 'hundredths is smaller than 'Tenths'.
So 8 hundredths is the smallest / least component of this decimal.
The number 8 in that question is the number with the least amount of value (0.008).
The 6
0 has the least face value, 2 has the least place value.
The lowest value digit is 2

It is 9
9
Well, honey, in the number 456802, the digit with the least value is 0. It's like the extra in a movie - it's there to fill space but doesn't really bring much to the table. So, yeah, that 0 is just hanging out, being all insignificant and whatnot.
The positional place values of digits in negative numbers are in ascending order from least to greatest as for example in the number -987 the least value digit is 9 and the greatest value digit is 7 because -900 < -80 < -7 The positional place values of digits in positive numbers are in descending order from greatest to least as for example in the number 987 the least value digit is 7 and the greatest value digit is 9 because 900 > 80 > 7
The negative three-digit number with the least value is -999.
