4. 0.6

The correct answer is: 0.4

To convert a percentage into decimal form, you divide the percentage by 100. In this case, 40% can be expressed as: 40 ÷ 100 = 0.4 This shows that the decimal representation of 40% is indeed 0.4. Thus, the fraction that represents 40% in decimal form is correctly identified as 0.4. In contrast, the other choices do not correctly represent 40% in decimal form. They are either higher or lower than the intended value. For example, 0.5 corresponds to 50%, 0.8 corresponds to 80%, and 0.6 corresponds to 60%.
