Which of the following represents the smallest amount: 0.400, 4.0, 0.04, 40?

Explanation:
Understand decimal place value and how trailing zeros work. Trailing zeros after the decimal don’t change a number, so 0.400 is the same as 0.4. Now you’re comparing four values: 0.4, 4, 0.04, and 40. The number in the hundredths place (0.04) is smaller than the number in the tenths place (0.4), and both are far smaller than 4 and 40. So the smallest amount is 0.04.
