Final answer:
To find the difference between 10.012 and 0.120, align the decimal points and subtract to get the answer 9.892. This is option 4 in the given choices.
Step-by-step explanation:
To subtract the numbers 10.012 and 0.120, you need to align the decimal points and subtract each digit in the corresponding place value, just like you would with whole numbers. Here's how it's done:
10.012
- 0.120
---------
9.892
After subtracting, the answer is 9.892. It's important to keep track of the decimal places to ensure accuracy. When you subtract in mathematics, especially with decimals, remember to line up the decimal points before performing the subtraction. If one of the numbers has fewer decimal places, you should add zeros at the end to match the number of decimal places in the other number. This answer corresponds to option 4.
