Mayday: Given that a, b are rational numbers and a+b, ab and a/b are equal, find the value of a, b. Mayday: If a, b are rational numbers, and a + b, ab and a / b are all equal, value of a, b.

Mayday: Given that a, b are rational numbers and a+b, ab and a/b are equal, find the value of a, b. Mayday: If a, b are rational numbers, and a + b, ab and a / b are all equal, value of a, b.

Ab=a/b
So a =0 or b =1 or b =-1
If a=0, b=0 is obtained from a+b=ab, but the denominator of b can not be zero.
If b=1, a+1=a a does not exist from a+b=ab
A-1=-a from a+b=ab if b=-1
Dejie
A =1/2
B =-1

The point 2.4 cm to the right of the origin on the number axis represents a rational number of 32, so what is the point 18 cm to the left of the origin on the number axis?

Let the point 18 cm to the left of the origin on the number axis be x.
The point 2.4 cm to the right of the origin on the axis represents a rational number of 32,
∴32
2.4= X
18. Solution: x=240.
Negative at 18 cm to the left of the number axis,
The point 18 cm to the left of the origin of the axis represents a rational number of -240.
