To determine if 0.4 is less than 1/2, we can compare the two values step by step.
1. **Understand the numbers**: 0.4 is a decimal number. The fraction 1/2 means one half of something, which can also be written as a decimal.
2. **Convert 1/2 to decimal**: To convert 1/2 into a decimal, divide 1 by 2. We get 0.5. So now we have:
- 0.4 (as a decimal)
- 0.5 (which is 1/2)
3. **Compare the two decimals**: Now we need to see which number is smaller. If we line them up:
- 0.4
- 0.5
4. **Finding the answer**: Since 0.4 is less than 0.5, it means that:
0.4 is less than 1/2!
So, the answer to the question 0.4 < 1/2 is true.
