When subtracting decimals, it's important to line up the numbers correctly. Let's look at how to set it up:

Make sure to write the numbers directly underneath each other. The decimal points should be aligned. This helps you keep track of the ones, tenths, and hundredths places.

Start with the rightmost digit, which here is the hundredths. It's 5 minus 0, which is 5. Write 5 below the line.

Next, calculate the digits one place to the left, the tenths. Here, it's 4 minus 7. Since 4 is less than 7, you need to borrow 1 from the ones place and write 10 above the tenths. That's because 1 one is equal to 10 tenths. Now 4 becomes 14, and you can subtract.

14 minus 7 is 7. Write 7 below the line.

Finally, subtract the ones. Since you borrowed 1 from the three, there are 2 left. 2 minus 2 is 0. Write 0 below the line and place the decimal point directly under the other decimal points.

The answer to the calculation$3.45-2.70=0.75$.
