For any positive x, y and z if x is n% of y and z is m% of y then what percentage must x be of z?	Choose one:	A) (n/m)%	B) (m × n)%	C) (100 / [m × n]) %	D) (100 × m/n)%	E) (100 × n/m)%
x is n% of y: x=n/100∗y   z is m% of y: z=m100∗y   What percentage must x be of z: xz∗100=n/m∗100   Answer: (100 × n/m)%.
