Flip the numerator and denominator. For example, reciprocal of 3/2 is 2/3.
a collection of symbols that jointly express a quantity
Use unit analysis to solve this problem. In one hour there are 60 minutes and in one day there are 24 hours. That is, hr/60min and day/24hr (The division can be pronounced "per", as in "60 minutes per hour" or "one hour per 60 minutes") Using these two terms, divide out the minutes and multiply in the days: 3500min * hr/60min * day/24hr The "min" units in the numerator of 35000 cancels out with the 60 min in the denominator of hr/60min. Same with the "hr". What you are left with is 3500 * 1/60 * 1day/24 Multiplying this out is approximately 2.43 with the unit of "days" left in the numerator.
The numerator is the top number in any fraction.
The process of writing units of each variable in a real-life problem is called dimensional analysis or unit analysis. It is useful for understanding the real-life problem and for checking to see we get a valid answer. Please see the links for additional explanations.
Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value
It is also called "Dimensional Analysis". It is a problem-solving method that uses the fact that any numbers can be multiplied by one without changing its value.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
Use dimensional analysis to solve this problem! 140 inches x (1 foot/12 inches) = 11.667 feet or (35/3) feet
