Temperature: Wild fish prefer lower temperatures but tank-bred specimens are happy over the range 72 to 77Â°F (22 to 25Â°C). It won't do well if kept in warmer water than this long-term, with the likelihood its lifespan will be reduced considerably. pH: 6.0 to 7.4.
Acid Test Ratio. The acid test ratio, sometimes called the quick ratio, is a liquidity ratio that measures a companys ability to pay off its current debts with only quick assets. Quick assets, sometimes called cash equivalents, are current assets that can be quickly and easily converted into cash in the current period.
Ratios can be divided into part-to-part ratios and part-to-whole ratios. Part-to-part ratios provide the relationship between two distinct groups. For example the ratio of men to women is 3 to 5, or the solution contains 3 parts water for every 2 parts alcohol.o calculate the amount of juice, we need the part-to-whole ratio of juice to punch. We are given the part-to-part ratio of seltzer to juice as 4 to 1. This ratio and the formulas provided above enable us to calculate the part-to-whole ratio of juice to punch as 1 to 5.
