Ratios integrate in one subject much of the material taught in elementary school: division, fractions, and their connection to real-life situations. Ratio problems are also useful since reality often obeys rules of constant ratios between quantities called "direct proportion" or "proportionality"…Arithmetic for Parents:A Book For Grown-ups About Children's Mathematicsdoi:10.1142/...
Other Real-Life Examples of Ratios Say for instance, you are in a classroom. In the classroom, there are 3 boys and 6 girls. The ratio of boys to girls is 3 6 = 1 2 or 0.5 It means that there are half as many boys as girls in the classroom. However, the ratio of girls to...
While you can do it with thebuilt-in meter in your camera, it is much easier and more accurate to use ahandheld incident light meter. You see, your in-camera meter takes a measurement of the light reflecting off your subject – whereas a handheld meter can measure the amount of light f...
2) Scenario Analysis:Liquidity ratios are used in scenario analyses where various financial situations are modeled to understand the potential outcomes. For instance, in a downturn, how would a company’s liquidity be affected if its Accounts Receivable collection were delayed? Or, what would happen...

Possible interactive effects of social judgments afforded by fWHR on self- and other-behavior may have consequences to these real-life situations as well. For example, when interacting with a stranger in a novel social context in which only limited information is available, first impressions may ...
Students model real-world situations that involve ratios with fractions in the numerator and/or denominator. They learn to connect the process of simplifying complex fractions with the algorithm for the division of fractions. They learn how to interpret simplified ratios as unit rates to solve real...
Converging lines of inquiry from across the social and biological sciences target the adult sex ratio (ASR; the proportion of males in the adult population) as a fundamental population-level determinant of behavior. The ASR, which indicates the relative
We did this because deviations from an equal sex ratio could be adaptive, for example, in situations of regular sex-biased mortality (e.g. seasonal mortality), which is well documented in many fishes (Balshine-Earn 1995; Godin 1995; Quinn and Buck 2001). We employed killifishes (15 ...
As a result, limited mechanistic interpretation hampers robust predictions for new situations. Studying interactions and functions within microbial inocula helps to optimize, interpret and extrapolate experimental findings associated with biodegradation to the community level (Kowalczyk et al., 2015), to ...
