Answer 3

To subtract 1 from 0.7, we can align the decimal points of the two numbers and then subtract each digit in turn, starting from the right:

markdownCopy code
   0.7
 - 1.0
------
  -0.3

As we can see, the result of subtracting 1 from 0.7 is -0.3. This means that 0.7 is less than 1, and the difference between them is 0.3, with a negative sign indicating that 0.7 is less than 1.

In other words, if you have 1 unit of something, and you take away 0.7 units, you are left with 0.3 units. Conversely, if you have 0.7 units of something, and you want to know how much more you need to make a whole unit, the answer is 0.3 units.
