What fraction of a radioactive nuclei remain after p half lives?
The remainder is 2-p or 0.5p of the original amount.

What fraction of carbon-14 will remain in the fossil of an organism that died 23080 years old?
Approx 6.1% remains.
How can you change a mix number to a fraction?
by multiplying the denominator with the whole number and adding the numerator. the denominator will remain the same.
ShayLea said that if you multiply the numerator and denominator of a fraction by the same number ou get an equivalent fraction Is this true Why or why not?
This is true; if you multiply both numbers by the same number, the proportion will remain the same.
What fraction of a radioactive nuclei remain after p half lives?
The remainder is 2-p or 0.5p of the original amount.
How much of one gram of radium-226 will remain unchanged after four half-lives?
After each half-life, half of the radium-226 will decay. Therefore, after four half-lives, 1/2^4 or 1/16th of the original gram of radium-226 will remain unchanged. This means that 1/16th of a gram, or 0.0625 grams, will still be unchanged after four half-lives.
How do you find how many atoms remain after 352 years of a radioisotope source containing 1.2E 06 atoms of plutonium -238?
176
What is the number of half lives that must past for only 1 of a particular radioisotope to remain?
This depends on this specific half life and the intial amount of sample.
What fraction of Carbon 14 will remain in charcoal burned in a primitive man's campfire approximately 28000 years?
Approximately 25% of Carbon 14 would remain in charcoal burned in a primitive man's campfire after about 28,000 years. This is because Carbon 14 has a half-life of around 5,730 years, so after multiple half-lives, only a fraction of the original amount will remain.
If a radioisotope has a half life of 400000 years and only 6.25 percent of the original radioisotope was present in a rock how old is the rock?
The rock is approximately 3.2 million years old. This can be calculated by dividing the half-life of the radioisotope (400,000 years) by the time it takes for 6.25 percent of it to remain (0.0625), which gives us 6 half-lives. Multiplying 400,000 by 6 gives us 2.4 million years, and since we need to account for the original amount as well, the total age of the rock is 3.2 million years.
