Answer:
6.25% of the original amount
Explanation:
half-life means that half is gone for every certain period of time. Because the half life is 1 month, only half of the 'radionulide' is left every month.
after 1 month= 50%
after 2 months= 25%
after 3 months= 12.5%
after 4 months= 6.25%

By comparing fossils of different primate species, scientists can study
how different species have diversified over time.<span> Almost all sediment is either laid down horizontally in
bodies of water like the oceans, or on land on the margins of streams and
rivers. Each time a new layer of sediment is deposited it is laid down
horizontally on top of an older layer. With this events, Geologists can
established a set of principles that can be applied to sediments and to
determine how these features evolved through time.</span>
