Decimal complements refer to the process of finding the complement of a decimal number with respect to a target number. In this topic, complements to 1, complement means the value that, when added to the given decimal number, will result in a sum of 1.
To find the decimal complement to 1, you can follow these steps:
For example, let's say we want to find the decimal complement to 1 of the number 0.75.
1 - 0.75 = 0.25
So, the decimal complement to 1 of 0.75 is 0.25.
Another example: Let's find the decimal complement to 1 of the number 0.412.
This is not as easy as the first example because the subtraction is harder:
1 - 0.412
Of course you can use a calculator to do this, but as mental arithmetic, the easiest way is to think of the digits after the point as a separate value, in this case 412. Because there are 3 digits, we subtract it from 1000, so we get 1000 - 412 = 588
Putting the decimal point back in, we can say:
1 - 0.412 = 0.588
So, the decimal complement to 1 of 0.412 is 0.588
