You cannot turn whole numbers into decimals, unless you add zeroes at the end like this- 500.00. You can only turn fractions into decimals

Answer:
Correlation.
Step-by-step explanation:
When relationship between two or more variables are to be established such that the measure of the effect of one variable (independent variable) on the other variable (dependent variable) is evaluated , this is called correlation study or analysis. In the scenario above, the relationship between productivity or revenue and employee shift is correlated, that is a relationship was established between the revenue made and the shift days of a particular employee, which yielded a positive association between the two variables. The employee shift is the independent variable and the revenue made is the dependent variable.

<u>Step-by-step explanation:</u>
While translating the problems into mathematical expression or mathematical expression in English, Kind of Expression can be used. Mostly in the algebraic parts.
Quotient: It represents that one value is divided by the another value. It is also known as the ratio.
i.e:
.
Product: It means multiplying either a known value and unknown variables or both unknown variables.
i.e.: 8b.
Sum: It means adding either a known value and unknown variables or both unknown variables.
i.e.:
