This paper summarizes our analysis of the complexity of ratio problems at Grades 6 and 7, and reports a two-year experiment related to the teaching and learning of rational numbers and proportionality in these grades. Two classes were followed and observed. Part of the teaching material was comm...
The purpose of this study is to explore Grade 9 learners' understanding of ratio and proportion. The sample consists of a group of 30 mathematics learners from a rural school in the province of KwaZulu-Natal, South Africa. Data were generated from their responses to two missing value items, ...
The proportion of infected colonies also did not dier signi®cantly between the two populations (Fisher exact test, P 0.38). The overall percentage of colonies without infected workers was 7.0%. The percentage of individuals infected was similar in the two populations. Sixty and 69%...

A higher proportion of assets compared to shareholders’ equity demonstrates the extent to which debt (leverage) is used in a company’s capital structure. An Example ROE and ROA are important components inbankingfor measuring corporate performance. Return on equity (ROE) helps investors gauge how...
We demonstrate how using a ratio-based profiling approach that scales the absolute feature values of a study sample relative to those of a concurrently measured common reference sample produces reproducible and comparable data suitable for integration across batches, labs, platforms and omics types. ...
Reversed gender ratio of autism spectrum disorder in Smith-Magenis syndrome Heidi Elisabeth Nag1,2* , Ann Nordgren3, Britt-Marie Anderlid3 and Terje Nærland4,5 Abstract Background: A substantial amount of research shows a higher rate of autistic type of problems in males compared to ...
There are other pitfalls to assessing E/A, for example, both E-wave and A-wave amplitudes are sensitive to cursor positioning, and the ratio decreases when the sample volume is moved into the mitral annulus or LA. High heart rates also create problems as diastasis is obliterated and the E...
