Question

Which of the following zero can be removed so that the value of the number remains unchanged.

• A. Zero in position 1
• B. Zero in position 2
• C. Zero in position 3
• D. All of the above.

Answer 1

The correct option is C Zero in position 3

Changing the zeros between non-zero numbers will change the value of a decimal number.

$87\underset{–}{0}76.\underset{–}{0}3520\ne 87\underset{–}{7}6.03520\ne 87076.\underset{–}{3}520$

Hence we can not remove zeros in the position 1 and 2.

But removing trailing zeros on the right end of a decimal point will not change the value of a number. So, removing zero in the position 3 will not affect the value of this decimal number.

$87076.0352\underset{–}{0}=8776.0352$

ten thousands	thousands	hundreds	tens	ones	.	tenth	hundredth	thousandth	ten thousandth	hundredth thousandth
8	7	0	7	6	.	0	3	5	2	0

Hence, option C is correct.
