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}\\](https://tex.z-dn.net/?f=x%20%3D%5Cfrac%7B-4%7D%7B5%7D%20%20%20%20%2C%20y%20%3D%20%5Cfrac%7B1%7D%7B-10%7D%20%3D%20%5Cfrac%7B-1%7D%7B10%7D%5C%5C)
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}](https://tex.z-dn.net/?f=x%20-%20y%20%3D%20-%5Cfrac%7B4%7D%7B5%7D-%20%28%20-%20%5Cfrac%7B1%7D%7B10%7D%29%20%3D%20-%5Cfrac%7B4%7D%7B5%7D%20%2B%20%5Cfrac%7B1%7D%7B10%7D%20%3D%20%5Cfrac%7B-8%20%2B1%20%7D%7B10%7D%20%3D%20%5Cfrac%7B-7%7D%7B10%7D)
