If 58 1/3% of a number is subtracted from itself we get 640.find 131 1/4% of original number is

Answer:
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:
x=a−b;y=a+b;x+y=2a;a=y−b=x+b;b=(y−x)/2=y−a
In addition to:
Perimeter of Square=4a
Area of Square =a2
Hypotenuse 2=a2+b2
Triangle=2a+H
Inequilateral Triangle=x+y+H
Rectangular Area=xy= a2−b2
Answer:
58 1/3%=7/12
remaining is 1-7/12=5/12
131 1/4℅=21/16
LCM of 12,16=48
5/12=5×4=20
21/16=3×21=63
20--------->640
63------–->?
640/20=32
32×63=2016.
