Answer:
1)For example we need to find 54 -41.2
Step 1: Write down the both numbers, one under the other, with the once digit in same line.
54
-41.2
Step2: Now,add zeros so the numbers to make the same length
.
54.0
-41.2
Step3: Then subtract normally, remembering to put the decimal point in the answer
54.0
-41.2
12.8
2)Here we need to subtract same place values of second number from the first number starting from right side, We can see to subtract 2 from 0 we need to take carry from 4 (4 will become 3)so that it will become 10 to subtract 2 from it ,thus we get our answer 12.8.
