Is dimensional analysis a method of problem solving that often uses conversion factors?
yes
What type of problem do you use for a reciprocal?
Flip the numerator and denominator. For example, reciprocal of 3/2 is 2/3.
In the problem solving process what are the standards used in analysis called?
Benchmark
How many days is 3500 minutes?
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.
What is an expression in math?
a collection of symbols that jointly express a quantity

What is a method of problem-solving that focuses on the units used to describe matter often using conversion factors called?
dimensional analysis
What is the process of writing units of each variable to a real-life problem called?
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.
Factor label method?
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.
When doing dimensional analysis when do you round to the correct number of significant figures?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
What is dimention analysis?
Dimensional analysis is a method in physics and engineering used to check the correctness of equations by examining their dimensions, or units of measure. By ensuring that the dimensions of physical quantities on both sides of an equation are consistent, dimensional analysis can help identify errors and verify the relationships between different variables. It is a powerful tool for understanding and deriving equations in science and engineering.
Is the numerator the parts in all in a fraction problem?
The numerator is the top number in any fraction.
How many grams of sodium are in 0.820 moles of Na2SO4?
na2so4= 142.05 g/mole, use dimensional analysis & set up your problem 13.64g
How much is 140 inches in feet?
Use dimensional analysis to solve this problem! 140 inches x (1 foot/12 inches) = 11.667 feet or (35/3) feet
What is the number that is to be divided in a division problem called?
Numerator
What do you do to the numerator in a lowest common denominator problem?
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
