Answer:

  6.4

Step-by-step explanation:

After rounding, you have ...

  300 × 8 / 300 × 0.8

  = 2400/300 × 0.8

  = 8 × 0.8

  = 6.4

_____

The Order of Operations requires we consider the 0.82 factor to be in the numerator. If you want it to be in the denominator, the denominator must be enclosed in parentheses.

The actual value is about 6.3656 when rounded to 5 sf, so this isn't a bad estimate.
