Question

is closure property satisfied and the rational number​

Answer 1

Answer:

(i) Closure Property : The product of two rational numbers is always a rational number. Hence Q is closed under multiplication. (a/b) x (c/d) = ac/bd is also a rational number.

Answer 2

Answer:

yes closure property is satisfied with only addition, subtraction and multiplication in rational numbers

Step-by-step explanation:

eg: addition= 3+3=6(rational number)

     subtraction= 3-4= -1(rational number)

      multiplication= 3*2=6(rational number)

  but in division, = 20/3= 6.666666666666666666and so on

     which is not a rational number
