We know that Harmie's average 5-day natural gas usage rate is 5.9 therms/5 days.

We have to calculate the 1 day average usage rate and 8 day average usage rate.

We can calculate this by transforming the denominator from 5 days, as it is in the information given, to 1 day and 8 days respectively:


\frac{5.9\text{ therms}}{5\text{ days}}\cdot\frac{1\text{ day}}{1\text{ day}}=(5.9)/(5)\cdot\frac{\text{therms}}{1\text{ day}}=\frac{1.18\text{ therms}}{1\text{ day}}
\frac{5.9\text{ therms}}{5\text{ days}}\cdot\frac{8\text{ days}}{8\text{ days}}=((5.9\cdot8)/(5))\cdot\frac{\text{therms}}{8\text{ days}}=\frac{9.44\text{ therms}}{8\text{ days}}

Answer: 1.18 therms / 1 day, 9.44 therms / 8 days [Option 1]
