Determines whether the expression expr is a fraction

There are many different concepts in the world of mathematics, and one of them is the mathematical fraction. A mathematical fraction is a numeric expression consisting of two integers: a numerator and a denominator separated by a dash. It is important to note that the denominator cannot be zero, because in this case the fraction will become indeterminate.

So, how do you determine if a given expression is a mathematical fraction? To do this, you can use a function that will accept an expression as a string and perform the appropriate checks.

This function takes as an argument an expression in the form of a string or a mathematical expression.

Thus, by using this function, you can quickly and reliably determine whether a given expression is a mathematical fraction. This can make your work easier when solving various mathematical problems or analyzing numerical data that require the use of fractions.
