Question

Verify the closure property of subtraction for any two rational number

Answer 1

The closure property states that for any two rational numbers a and b, a – b is also a rational number.

\frac{1}{2} – \frac{3}{4}

= \frac{4 – 6}{8}

= \frac{-2}{8}

Or, = \frac{-1}{4}

The result is a rational number. So the rational numbers are closed under subtraction.

Answer 2

if a and b two rational numbers

then we find a rational number with respect to subtraction
