Explanation:

When I was taught to solve fractions, I used "Cross Multiplication." How to use cross multiplication is to multiply the first numerator with the second denominator, and the first denominator with the second numerator. To make it easier, if the question was this, #x/y = a/b# you'd have #ya# and #xb#. So what you do with those numbers is make them equal. Let's put in your problem. #6/14 = t/84# If you cross multiply, you get #14t# and #504#. To get #t#, you make them equal. If you divide both sides by 14, you get #t# and #504/14#. #504/14# is also #36#, making the answer #36#.
