Replace missing values with the mean/median value of the feature in which they occur. Label encode NAs as another level of a categorical variable. Run predictive models that impute the missing data. Furthermore, what is a ratio problem? Ratio problems are word problems that use ratios to relate the different items in the question. The main things to be aware about for ratio problems are: Change the quantities to the same unit if necessary. Write the items in the ratio as a fraction. Keeping this in view, what is a ratio table? A ratio table is a structured list of equivalent (equal value) ratios that helps us understand the relationship between the ratios and the numbers. Rates, like your heartbeat, are a special kind of ratio, where the two compared numbers have different units. Let’s look at some examples of ratio table problems.What is the formula for ratio and proportion?It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as “twenty is to twenty-five as four is to five.” In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion.
