30-1.5 Explain

Answer: 30-1.5 = 28.5.

To explain this, we can break it down into smaller steps. First, we can subtract the whole numbers: 30 – 1 = 29. Then, we can subtract the decimals: 29 – 0.5 = 28.5.

Another way to explain this is to think about it in terms of money. If you have 30 dollars and you spend 1.5 dollars, you will have 28.5 dollars left.
