The three different improper fractions of 4 1/2 are 9/2, 18/4, and 36/8.
To express the mixed number 4 1/2 as three different improper fractions, we need to convert it to an improper fraction first. A mixed number consists of a whole number part and a fraction part.
Converting 4 1/2 to an improper fraction:
We multiply the whole number (4) by the denominator of the fraction (2) and add the numerator (1) to get the new numerator. The denominator remains the same.
Improper fraction: (4 x 2 + 1) / 2 = 9/2
Now, we can represent 4 1/2 as three different improper fractions:
9/2 - The original improper fraction we calculated.
18/4 - We multiplied both the numerator and denominator by 2 to get an equivalent fraction.
36/8 - We further multiplied both the numerator and denominator by 2 again to get another equivalent fraction.
All three improper fractions are different representations of the mixed number 4 1/2. They have the same value but are written with different numerators and denominators.

Answer:
Natural, Whole, integer, rational, real
Step-by-step explanation:
Here, the given number,
We can write,
∵ 121 and 11 are integers also, 11 ≠ 0,
So, is a rational number,
⇒ is a rational number,
Now,
11 is a whole number,
⇒ is a whole number,
Again, a whole number is always a natural number and a positive integer ,
⇒ is a natural number or an integer,
All numbers ( rational or irrational ) are called real number.
So, we can also write,
is a real number.
The method to solve an equation is
There are three methods used to solve systems of equations: graphing, substitution, and elimination
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

The three methods used to solve systems of equations: graphing, substitution, and elimination
Solving an equation by Graphing :
Simply graph the provided equations and discover the point(s) where they all cross to solve a system. The coordinate of this point will provide you with the values of the variables you are attempting to solve for. This works well when the equations are already in slope-intercept form.
Solving an equation by Substitution:
Substitution is best used when one of the equations is in terms of one of the variables. Once an expression for the variable has been found, substitute or plug it into the other equation where the original variable was to solve for the next variable's integer value. The final step is to substitute the discovered number value for its corresponding variable in the original equation.
Solving an equation by Elimination:
Elimination is the process of combining the equations to obtain an equation with only one variable. This is only possible if the coefficients of one variable in both equations are diametrically opposed and will cancel each other out when put together.
The next step would be to use the equation we devised to determine the variable's value, and then plug that value back into the original equation to determine the remaining variable.
Hence , There are three methods used to solve systems of equations: graphing, substitution, and elimination
