Question

For rounding of decimal numbers, if the first digit that is to be dropped is $5$ or , we add $1$ to the last digit that is kept.

• A. more
• B. less
• C. equal

Answer 1

The correct option is A more

Let's take an example of rounding off to the nearest tenths.

Here, the last digit to be kept is in the tenth column.

The first digit to be removed is located one place right to the last digit to be removed.

Here, the first digit to be removed is in the hundredth column, i.e., 5.

We know that if the first digit is 5 or more, add 1 to the last digit.

Here, first digit is 5.

$\therefore$ Add 1 to the last digit, i.e., $2+1=3$

Round off number is $9.7$.
