Answer 2

Answer:

i) 15.654 is 15.7

ii) Can not be done.

iii) 6.00 x 10⁵.

Explanation:

In the given question,

i) 15.654 upto 3 digits :

To round off the given number upto 3 digits we have to check the 4th digit whether that is less than 5 or greater than or equal to 5.

So,

15.654 is 15.7

ii) 1426 upto 5 digits :

This number can not be rounded off to 5 digits as the number contains only 4 digits.

iii) 5.996 x 10⁵ upto 3 digits :

This number can be converted to 6.00 x 10⁵ because 9 is greater than 5.

So,

5.996 x 10⁵  is  6.00 x 10⁵.
