To disinfect 1 quart of stream water to make it drinkable, you need to add 2 tablets of iodine. How many tablets do you need to disinfect 4 quarts?
Answer (2)
Good morning,
We want to disinfect 4 quarts of stream water: 4 4 = 1
So:
2 t ab l e t s 4 1 o f w a t er = x t ab l e t s 1 o f w a t er 8 1 = x 1 x = 8 t ab l e t s
Answer: We need 8 tablets.
You need 8 tablets of iodine to disinfect 4 quarts of stream water because 2 tablets are required per quart. Multiplying the number of tablets for 1 quart by 4 gives you the total for 4 quarts. Hence, the calculation is 2 tablets × 4 quarts = 8 tablets.
