Answer: Yes, the set of real numbers is closed under addition.
Explanation:
Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.

You want to find out how many cups of flour Jaylin needs to make 30 biscuits.
We currently know 2 cups of flour makes 20 biscuits.
We can halve the recipe down to make it simplier - simply divide all ingredients by 2 to halve it.
1 cup of flour = 10 biscuits
Since 1 cup of flour equals 10 biscuits, and 2 cups of flour equals 20 biscuits, we can safely say 3 cups of flour equals 30 biscuits.
