Question

Using two different instruments, I measured the length of my foot to be 27 cm and 27.00 cm. Explain the difference between these two measurements.

Answer 1

They are the same. They are both centimeters and they are the same whole number, since the second measurement is just 27 as well. Your feet are the same size. :P

Answer 2

You need to specify what instruments were used.

Answer 3

They're not the same. The difference is 2 whole significant digits
