Final answer:
After converting 2000 milliliters to liters, we find that Mrs. Reyes's children added 2 liters to the kiddie pool. The pool initially contained 83 liters, so now there are 85 liters of water in it.
Step-by-step explanation:
Mrs. Reyes initially filled a kiddie pool with 83 liters of water. Her children later added 2000 milliliters (ml) of water to the pool. To determine the total amount of water now in the pool, we must first convert milliliters to liters because the metric system uses liters as a more common unit for such measurements of capacity. Since 1000 milliliters is equal to 1 liter, we convert 2000 milliliters to liters by dividing by 1000.
2000 ml ÷ 1000 = 2 liters
Now, we add the 2 liters to the original 83 liters:
83 liters + 2 liters = 85 liters
Therefore, there are now a total of 85 liters of water in the kiddie pool after the children's addition.
