Fractions

I find it extremely interesting that most teachers were not able to give the correct answer to the fraction problem. Fractions may take some time to understand, but a teacher should be able to understand and implement a problem regarding fractions. Also, does putting a fraction into story form confuse teachers and so they are not able to put in the correct way? I believe that teachers need to make sure they are not getting confused with connecting the symbols to elements in the story and then…

the interaction between the ligand and the target protein so that LDH proteins could elute down. Through this elution process, 20 fractions were collected after 1M NaCl was added and LDH spot test was performed. Graph 1: Plot of elution volume Vs the absorbance at 280nm. LDH Spot Test A1-A2 – Positive and negative control respectively. B1-B10 – Collected Fractions 1-10…

These will include changes in the depreciation expense, fixed assets as a fraction of the previous year’s total assets, and depreciation expense as a fraction of assets. a. Depreciation expense as a fraction of the former year depreciation expense According to OI’s annual reports, the depreciation expense for 2015 was $319 million while that of 2014 was $331 million. The percentage of 2015 depreciation as a fraction of 2014 depreciation = 319 /331 = 0.96 For Anchor Glass Container Corp, the…

of three lessons shown in this document is developed for year 7 Mathematics classes of a state school located in the outer suburb of Brisbane. These lessons are made of engaging teaching episodes and a formative assessment, to teach operations on fractions. A part of the material used is drawn from chapter 4 of the textbook (Greenwood et al., 2016). Remaining resources are hands-on activities, to make lessons engaging, sourced out from Internet. The school, considered for developing this…

simply to show it in fraction form, making the conversion easier. The number is then set equal to the fraction representing the number of pounds in a kilogram (kg). The 2.22lbs. is placed on the bottom part of the fraction in order for the lbs. units to cancel out, leaving behind only kilograms. The numerator of the first fraction is multiplied by the numerator of the second fraction. This product is then divided by the product of the denominators of both the first and second fractions, leading…

procedure, two main fractions obtained from BSG, PER-BSG and SUPER-BSG. The yield and chemical composition of BSG and its fractions are summarized in Table 1. The yield of BSG was ~10%. PER-BSG and Super-BSG fractions yield was 69% and 31%, respectively. There was no significant…

one hundred percent. With the pre-test it showed that I needed to teach how to write the fractions using sets, shading in the correct fraction, writing in the fraction for the shaded portion, and figuring out which is the numerator and denominator. When looking at specific students’ tests, I saw the struggle of answering questions and some students who attempted questions but had no comprehension of fractions. Some students took a…

B Sridhar et al (2012) studied Purification and Characterization of Biosurfactants. The emulsifications of biosurfactants were checked in various oils such as olive, coconut, sunflower and rice bran oils, the emulsification activity of biosurfactants. Pseudomonas aeruginosa had higher emulsification activity than Saccharomyces cerevisiae. While checking the sugar and lipid content in biosurfactants by phenol sulphuric acid method and vanillin reagent method, found high in Pseudomonas aeruginosa…

solving exponential equations. The hardest concepts were learning the different product of powers because I would mix them up. Concepts (Highlight and Explain): (1) Converting a fraction into a decimal 1 Weak 2 3 4 5 6 7 8 9 10 Strong Explain how to do the concept: To convert a fraction into a decimal you have to divide the smaller number by the larger number(adding zeros to the number if needed) and the answer of the equation would result into your decimal.…
