Why do we need to have common denominators when adding fractions?

1 answer:

3 0

So that we have the right answer once we do the addition
Say that I measure my self at 12 feet with one measuring stick, and go on with another measuring stick that tells me I'm 3 meters tall, if I added those, I would be at something like 15/46 or something like that. See that would be wrong. We would want the right denominator so that it could be easier and also correct.

Transuranium elements are elements larger than uranium that are produced via transmutation.

True. Atoms with atomic numbers higher than 92 are not very stable and have half lives shorter than the age of the earth so they are not found naturally. Due to that, the process of transmutation must be used to get atoms with the atomic number higher than 92.
