What is the algebraic expression for four divided by the difference between a number?
You don't have the complete question here. "...between a number" and what? First figure out what operation is being used, and then put that operation in the place of the "and" in the statement.

The operation isalso the heart and soul of measurement-unit conversions.It means that if you spot a numerator and denominator that have a common factor, then you should divide the numerator and denominator by their common factor.This operation doesn't change the value of an expression, but it 'simplifies' it. The operation is also the heart and soul of measurement-unit conversions.It means, if you can cancel, cancel. Otherwise don't.This usually refers to simplifying fractions that involve numbers or variables. If the same variable, or factor, appears in the top and in the bottom, you can eliminate it from both without changing the result.
