A salt drying field can dry 3 grams of salt with 100 grams of seawater. If a salt field puts 585,000 tons of seawater at a time, how many tons of salt can it dry?
Solution: If you put 585,000 tons of seawater, you can dry X tons of salt; Y tons of seawater can produce 9 tons of salt.
3: 100=x:585000
100x=3×585000
100x= 1755000
x= 17550
3: 100=9:y
3y=9× 100
3y=900
y=300
A: If you put 585,000 tons of seawater, you can get 17550 tons of salt. 300 tons of seawater can produce 9 tons of salt.
