Question

write the smallest possible length. length:9.15 (to 2 decimal places)

Answer 1

9.145 is the smallest value that will round to 9.15.

As the rule that if that digit is less than 5, do not change the rounding digit but drop all digits to the right of it. So it should be 5 to 9 but then the question above is looking for the smallest possible number which is 5. 

Answer 2

Answer:

The smallest possible length of 9.15 rounded to 2 decimal places is 9.145

Step-by-step explanation:

When you round a number to 2 decimal places you round the 3rd decimal place to the nearest integer, then numbers 9.140, 9.141,  9.142, 9.143 and 9.144 are rounded to 9.14, and numbers 9.145, 9.146, 9.147, 9.148 and  9.149 are rounded to 9.15.
