Before answer this question, you need to know what is the half-life of a compound, the term half-life is defined as the time it takes for one-half of the atoms of a radioactive material to disintegrate. Knowing this you know that has passed half of the half-time, so you should probably have 25% of the original amount of 235U. This problem may be tricky because it says half of the time to reach the half-time, but 50% of the compound will be present in 750 million years after the death of the specimen.
