Question

henry said that to subtract two decimals, you can ignore the decimal points, subtract the numbers, and then put the decimal point back. Do you agree or disagree? Explain.

Answer 1

Disagree

Step-by-step explanation:

No, I disagree with Henry.

To subtract two decimal we cannot ignore the decimal points in all cases. It will yield to wrong results after subtraction if we choose to put the decimal point back later.

Examples :

let's consider two numbers 15.555 & 0.05

Correct Method of Subtraction Gives :

15.555 - 0.05 = 15.505

Henry's method of Subtraction Gives :

15555 - 5 = 15550

After putting decimal back we might get 15.550 or 155.50.

Hence, we can clearly see that this method is giving incorrect and ambiguous results.

Hence, I completely Disagree.
