simple the first question is in an incorrect format to be asked in the fashion it is delivered. To make it to answerable it needs to be put in proper arithmetical form by either a>providing a set of brackets to denote if the fractions denominator is separate from the parenthesis b> provide a set of brackets to denote that the denominator contains the parenthesis or c> write the fraction in its proper form with a number over the other instead of the incorrect form of using the back slash [spoiler]i love people posing these since it is unanswerable due to the faulted arithmetic of the presentation [/spoiler]
