Question

verify closure property of subtraction for the following rational numbers x=4/11,y=-7/8
Step by step
​

Answer 1

Answer:

here, to verify closure property of subtraction of rational numbers,

x-y where x and y are rational numbers should give a result as a rational number

so, here,

$\frac{4}{11} - \frac{ - 7}{8}$

$= \frac{32 - ( - 77)}{88}$

$= \frac{32 + 77}{88}$

$= \frac{109}{88}$

here, x is a rational number, y is a rational number and x-y i.e 109/88 is also a rational number

so, the closure property of subtraction of the given rational numbers are verified
