But on her desk was a secret weapon: a stack of worksheets -- the antithesis of constructivist math -- pages of classic problems in long division, the addition of fractions and reducing the sum of fractions to its simplest terms.
The non-mobile fraction was in the range 0.003 – 20.2 mg/kg corresponding to 1.2 – 48.5% of the sum of fractions.
Obviously, it seems, the sum can be rewritten (1 − 1) + (1 − 1) + … = 0 + 0 + … = 0. Surely this answer seems as intuitive as the sum of fractions.
Therefore, the unit of the sum of fractions is, that is, every fraction signifies a frequency at which slots are scheduled.
Figure 6 Spatial distribution in weight of mobile (a), semi-mobile (b) and non-mobile Hg species (c) related to the sum of fractions.
For example, if the precision of the fractions is 128 (the lowest possible fraction is ), the sum of fractions can be expressed as (128 × 1/4)+(128 × 1/32)+(128 × 1/64), or simplified as 32+4+2.
When two (or more) methods tie for the same position in the ranking, they obtain the same label; thus the sum of fractions at certain rankings may exceed 100%.
A statistically significant increase in Cu and Zn total concentration (assessed by the sum of fractions) was noted only within the 0 5 cm soil layer for the 50 and 100 m3 ha− 1 year− 1 (PS50 and PS100) treatments, and up to 10 15 cm for the 200 m3 ha− 1 year− 1 (PS200) treatment.
In order to assess the fraction of Cr III) and Cr VI), a sum of each fraction was set to unity, and each fraction was multiply to CN of each Cr path.
We limited our analysis to time points when the total fraction of acetylated histone (the sum of the fraction acetylated for every residue) was less than 10% of the initial substrate concentration.
