Is -96 1/5 a rational number

yes

Step-by-step explanation:

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers

yes

Step-by-step explanation:

1/5 is a rational number because when you convert it into decimal form, it is a terminal decimal; 0.2. 
Hope that answered your question.

[tex]\frac{1}{5}[/tex]is a rational number because it can be put as a fraction. An Irrational numbers cannot be a fraction since they are continuous (unless you estimate/round them up)  

Yes

Step-by-step explanation:

a) False. b) False. c) No, it's Rational. d) pi=355/113 e) 5i (for Complex Set of Numbers)

Step-by-step explanation:

a) Since there is the empty set. And an axiom assures us the existence of this Set. "There is a set such no element belongs to it"

∅ has no elements.

b) A perfect number is a positive integer equals to the sum of proper divisions

The smallest is 6. Since the proper divisors of 6={3,2,1}. 6=1+2+3

28 is a perfect number, but not the smallest. It is perfect since

28 proper divisors={14,7,4,2} 28=1+2+3+4+5+6+7

c) No, An Irrational number cannot be written as a fraction a/b where "a" and "b" are integers. 1.5 is a rational one, since 3/2 =1.5

d)

[tex]\pi[/tex]=22/7 -1/791= 355/113

e)  Not for Real Numbers, since it is not defined for Real numbers. But for the set of Complex 5i

yes, 1/5 is a rational number

Step-by-step explanation:

1/5 is a rational number because both 1 and 5 are integers
