There is no such thing as one-forth. But one fourth 5 is 1/20.
Four divided by one and one fourth = 16/5 or 31/5
The only way it can be simplified is to one and one fourth
Since half of the atoms of the original substance will have decayed after 5 hours, half of what is left will have decayed after the next five hours. The answer is 0.25 or one fourth of the original atoms will remain.
The number that is one fourth of one half of one fifth of 200 is 5.
one and one fourth = 1 1/4 or 5/4
