Question

1. Verify the closure property of rational numbers (addition, subtraction, multiplication and division) for −9/ 11 and 3/ 5

Answer 1

Step-by-step explanation:

For addition = (-9/11 ) and (3/5)

= (a/b + c/d)

= (-9/11)+(3/5)

= (-45 + 33)/55

= -12/55

For subtraction

= (a/b - c/d)

= -9/11 - 3/5

= (-45 -33)/55

= -78/55

For multiplication

= (a/b×c/d)

= -9/11 × 3/5

= -27/55

For division

= (a/b ÷ c/d)

= -9/11 ÷ 3/5

= -9/11×5/3

= -15/11
