Checks whether the given node logically represents multiplication by a fraction of `1`.
For example, `a * 1` in `a * 1 / b` is technically multiplication by `1`, but the
whole expression can be logically interpreted as `a * (1 / b)` rather than `(a * 1) / b`.
@param {BinaryExpression} node A BinaryExpression node to check.
@param {SourceCode} sourceCode The source code object.
@returns {boolean} Whether or not the node is a multiplying by a fraction of `1`.
