A typical household in Australia uses 260 000 L of
water each year. A quarter of the water is used for showers. Typically a shower uses 40 L of water.
About how many showers do they have in a year?
Order the steps of the solution.
a.  Determine the number of showers the typical Australian
household takes each year.  b.  Determine the number of showers by dividing the amount of water
used in showers by 40. 65 000 ÷ 40 = 1625. Check 1625 x 40 = 65 000.  c.  The typical
Australian household takes about 1625 showers each year.  d.  Determine the
amount of water used in showers by dividing the amount of water used in a year by 4. 260 000 ÷ 4
= 65 000. Check: 4 x 65 000 = 260 000.
