Verify this closure property of subtraction x= -4/5 , y= 1/-10​

Mathematics
1 answer:
Rom4ik [11]3 years ago
4 0

Answer:

x - y is also a rational number. Hence satisfies the closure property.

Step-by-step explanation:

x =\frac{-4}{5}    , y = \frac{1}{-10} = \frac{-1}{10}\\

Closure property of subtraction states that for any two integers a and b, (a - b) must also be an integer.

Here x and y are rational numbers. so x - y must also be rational to satisfy the closure property.

              x - y = -\frac{4}{5}- ( - \frac{1}{10}) = -\frac{4}{5} + \frac{1}{10} = \frac{-8 +1 }{10} = \frac{-7}{10}
