Write a function to translate the string and calculate the value. Hyphens will always be present between top and bottom values of fractions while \"of\" can be replaced by a multiplication symbol. Also, make sure you capture singular and plural fractions. In this case, the translated string might look something like this:</w:t></w:r></w:p><w:p><w:pPr><w:pStyle w:val=\"ListParagraph\"/><w:numPr><w:numId w:val=\"1\"/></w:numPr></w:pPr><w:r><w:t>1/7 * 2/9 * 630</w:t></w:r></w:p><w:p><w:pPr><w:pStyle w:val=\"text\"/></w:pPr><w:r><w:t>which, when evaluated, will yield 20.
