Answer:
11 over 9

Explanation:
What is a fraction?
A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
To solve for
, we need to first convert these fractions so that they share a common denominator.
What is a common denominator?
A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
If a common denominator just refers to 2 fractions having the same denominator, we can simply multiply the numerator and denominator of the fraction
by a number. To solve for that number, we can divide 9 by 3.
Now that we know that the number is 3, multiply both by 3.
Now the fraction looks like this:
.
We can now change the expression to this:
When adding fractions with the same denominator, we can just add the 2 numerators and keep the common denominator the same.
Now just insert 11 in as the numerator:
Therefore 2 over 5 plus 5 over 9 is 11 over 9.
