Are sets of fractions closed under addition?
Yes.
Are odd numbered sets closed under addition and multiplication?
No. 1 + 3 = 4, which is not odd. In fact, no pair of odds sums to an odd. So the set is not closed under addition.
What is the two kind of sets?
Closed sets and open sets, or finite and infinite sets.
What is the kinds of sets?
Closed sets and open sets, or finite and infinite sets.
What is an equation that's sets two fractions equal to each other?
They are equivalent fractions as for example: 3/4 = 9/12
Are sets of fractions closed under addition?
Yes.
What sets of numbers are closed under addition?
I know that whole numbers, integers, negative numbers, positive numbers, and even numbers are. Anyone feel free to correct me.

If you add two closed sets is the result also closed?
No, it is not.
How do you write a whole number as imprper fractions?
You cannot: whole numbers and improper fractions are disjoint sets.
Borel sets must contain the closed subsets of R?
yes, since every closed set can be written as a intersection of open sets. (Recall that borel sets is sigma algebra)

Which sets of numbers are closed under subtraction?
To be closed under an operation, when that operation is applied to two member of a set then the result must also be a member of the set. Thus the sets ℂ (Complex numbers), ℝ (Real Numbers), ℚ (Rational Numbers) and ℤ (integers) are closed under subtraction. ℤ+ (the positive integers), ℤ- (the negative integers) and ℕ (the natural numbers) are not closed under subtraction as subtraction can lead to a result which is not a member of the set.
