Which decimal is the smallest amount 0.0003 0.003 0.03 0.3?

Answer 1

.0.0003

Answer 2

To compare numbers starting with the highest place value column compare the digits, moving right a place value column until either all digits have been considered or one digit is higher than the other. If a place value column is empty, its digit value is 0:

The highest place value column with a non-zero digit across the numbers is the tenths column (the column immediately after the decimal point).

The tenths digits are 0, 0, 0, 3 respectively, 3 is greater than 0, so 0.3 is the greatest.

We can now ignore 0.3 as it is the greatest, and continue with the next column to the right, the hundredths, to sort the rest: the digits are 0, 0, 3 respectively; 3 is greater an 0, so 0.03 is the next greatest number

We can now ignore 0.03 and continue with the next column to the right, the thousandths: the digits are 0, 3 respectively; 3 is greater an 0, so 0.003 is the next greatest number.

This just leaves 0.0003 which is the least.

Therefore 0.3 > 0.03 > 0.003 > 0.0003

So the smallest amount is 0.0003

Answer 3

0.0003

Answer 4

0.3
