What does it mean to evaluate the expression?

Evaluating Expressions. "Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question.

Regarding this, how do you evaluate this?

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

How do you evaluate a fraction?

To evaluate an expression means to find its value. Check that the fractions all have the same common denominators. In this example, they all have a common denominator of 10. When the fractions all have a common denominator, ignore the denominator and evaluate the numerators.
