How do you use your water indoors? On average, 3/14 is used for showering and bathing, 1/7 is used for laundry, 1/28 is lost to leaky toilets, and 3/28 is used for dishwashing and faucets. Where does the rest go? Toilet flushing! What fraction of the water is used for toilet flushing?

first, let's change everything to a common denominator so it's easier to add:

3/14=6/28

1/7=4/28

1/28=1/28

3/28=3/28

 

so we have 6/28+4/28+1/28+3/28=14/28=1/2

 

so the other 1/2 is used for toilet flushing!
