* Write decimal as a fraction by putting 1 as denominator, so 4.875/1
* Multiply numerator and denominator by 10 x 10 x 10 to get 4875/1000
* Simplify the fraction so it gets 39/8
* Turn into a mixed number and get 4 7/8
The decimal number 4.875 is equal to the fraction 4 7/8.
The decimal number 4.875 can be expressed as a fraction in the following way:
4.875 = 4 + 0.875
The whole number part, 4, can be written as a fraction with a denominator of 1: 4/1.
The decimal part, 0.875, can be expressed as a fraction by considering the digits after the decimal point.
Since there are three digits after the decimal point, we can place the decimal number over a denominator of 1 followed by three zeros: 875/1000.
Combining the whole number and decimal parts, we have:
4.875 = 4 + 0.875 = 4 + 875/1000
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 125:
4.875 = 4 + 875/1000 = 4 + (875/125) / (1000/125) = 4 + 7/8
Therefore, the decimal number 4.875 is equal to the fraction 4 7/8.

Final answer:
A function is a concept in mathematics that assigns every value of an independent variable to exactly one value of a dependent variable. In other words, for any given input (or 'x' value), there is only one output (or 'y' value).
Explanation:
A function in mathematics is a rule that assigns each value of the independent variable to exactly one value of the dependent variable. This means that for any given x (independent variable), there is only one y (dependent variable).
Consider a linear equation y = mx + b, where m and b are constants, x is the independent variable, and y is the dependent variable. When we substitute different x values in the equation, we obtain different y values. However, each x value gives exactly one y value, illustrating the definition of a function.
Another example refers to a statistical context: y = a + bx, where a and b are constants. It also depicts the same relation - each independent variable x produces one dependent variable y.
