Answer:
The decimal is not a rational number.
REASON:
A decimal can be a rational number if it fulfills any of the two conditions.
It must be Terminating. This means that the decimal should have finite number of digits.
If it is non-terminating decimal it should be Recurring. This means the decimal should repeat itself after some specific digits.
W=340-z (vice versa)
x=540-w (vice versa)
y=-150+x (vice versa)
z=-50+y ( vice versa)
2,304 because 2x4 is 8x6 is 48^2 is 2,304
