11.)d
Step-by-step explanation:
1) d
The additive inverse of 25/52 = -25/52
-25/-52 = 25/52 both are same numbers.
So they are not Additive inverse to each other.
2) There is no correct option
There is no pair of reciprocals to each other in the following
3) b
Given that -3/5 ×8/11
=> (-3×8)/(5×11)
=> -24/55
Multiplicative Inverse of -24/55 = -55/24
4) c
Given 165/-275
=> -165/275
=> -(3×55/(5×55)
=> -3/5
5)d
Given that -16/18
Denominator = 18
Given denominator = 162
=> 162 = 18×9
Required Numerator = -16×9 = -144
6)c
Given 25/35
=> 5/7
On multiplying with 13 both numerator and denominator
=> (5/7)×(13/13) = 65/91
7)d
A rational number can be a terminating decimal if it's denominator has factors 2 or 5
8)c
Given numbers are -2/5 and -4/5
Their product = (-2/5)×(-4/5)
=> (-2×-4)/(5×5)
=> 8/25
9)b
Given numbers are -4/5 and 14/5
Their sum = (-4/5)+(14/5)
=> (-4+14)/5
=> 10/5
=> 2
10)b
There are infinitely number of many rational numbers between any two numbers is called Densitive Property.
11)a
Given number = 0/1 = 0
Multiplicative Inverse of 0 = 1/0 =not defined or Undefined since The division by zero is meaning less
