Based on the pretest sample, prior math research, and our previous findings, we anticipated students would make the most mistakes in Combining (C: Student combines numerators together and denominators
together), Add All (AA: Student adds together all the numbers of the fractions and finds a total sum), Select Denominator
(SD: Student uses one of the denominators
in the answer without finding the equivalent fraction), and Equivalent Fractions (EQ: Student makes an error when attempting to find an equivalent fraction).
Using the exposure-based denominators
provides risk estimates.
Patriotism is a much more attractive common denominator
as people from different ethnicities live intermingled everywhere in a country of 75 million.
So far they should have discovered that the decimal expression of the fraction in fundamental form will terminate when the denominator
is 2, 4, 5, 8 or 10.
The method of Gutman et al  and Lucas method cannot be implemented for this system as per their limitation that they are not applicable whenever the order of the denominator
n of the original system differs from its numerator order m by more than one for m < n.
When a number is found that is a multiple of both denominators
, the fractions are then expressed in terms of the common denominator
, so 2/5 is 8/20 and 3/4 is 15/20.
Once the standard cost centers are established, the amounts posted to those cost centers on individual projects would be related to specific common denominators
is plate appearances, so the equation measures simply the number of bases a batter gets per plate appearance.
By sorting that list against other common denominators
, the company can direct its distributors to the prospects most likely to buy today's products.
Both EDs focused solely on determining the number of shares in the EPS denominator
