If 58 1/3% of a no. is subtracted from itself we get 640. Find 131 ¼% of the original number?

Answer:
This is a fine example of
Algebra should use only when essential [to resolve]
Operations as listed, need not explicitly use to acquire same results
In this 3rd grade example, where algebra is not necessary, but using your head is, rest assured many will recommend using x, y, n, N, D, a and b and others too anyway.
I refer to these sorts as: Askholes, as they need explicit instructions to do mostly anything, are incapable of independent cleverness or thought, and oft are alike a pesty fly who can't locate the window he flew in from, when you inform they these 3 facts.
Add atop comments about: Imaginaryland, the Job Fairy and other Sarcasms about their degrees, they become even worst.
So, Rather than being an askhole, instead, on this you use
Number= 756÷(5/3)=756×(3/5)=756×.6=453.6=No.
No.×.875=The Next Number=453.6×.875=453.6-[56.7]=396.9
It is not technically algebra, but easily could be a 10 question exam or pop quiz by the geometry behind the scenes or if there was any real necessity to know that additional info, via:
.875x=y=[.875(756(3/5))]
Discern x, y, a, and b by the information provided in addition to the general basics you should already know of:
