Radioactive Isotope help?

Suppose that you start with 100 grams of a certain radioisotope that decays to half its original amount in 50,000 years.

In 0 years, it has an amount of 100 grams of parent material and 0 grams amount of daughter material.
In 250,000 years, it has an amount of 3.125 grams of parent material and 96.875 grams of daughter material.

Can you tell me the amount of parent material and amount of daughter material for each of the following year:?

50,000
100,000
150,000
