1 .). Rational Numbers are often represented by Fractions.


2.). Real Numbers are usually represented as Decimals.


3.). A Percent is an uber specific way to represent a fraction with a denominator.


4.). Scientific Notation:

Interprets ==> Notation that has been generated.

Perform ===> Operations with numbers expressed in Scientific Notation.

Use =====> To determine units of appropriate size for measurements of very Large, or very Small Quantities.



35,036 1 / 3

Scientific Notation/Standard Form:

35,036

Expanded forms can be written like a sentence or stacked for readability as they are here.

Expanded Notation Form:

30,000 + 5,000 + 0 + 30 + 6

Word Form:

T thirty-five thousand, thirty - Six, and One third


35, 036 1 / 3:

Decimal =======> 35.36 1 / 3 =======> 11678.66667

Fraction ======> 35036 1 / 3

Scientific Notation/Standard Form: 30,000 + 5,000 + 0 + 30 + 6

Percentage: ======> 3,503,633.33% =====> 1 / 3 =====> 0.3333333....

Step by Step Solution:

Given Input Number : 1 / 3

= 1 * 10 + 3 * 1

= 1 * 10 + 3 * 1 * ( 10 / 10 )

= ( 1 + 0.3 ) * 10

= 1.3 x 101


5.). Scientific notation and exponential notations are one and the same. Writing numbers based on powers of ten is called exponential notation. It simplifies numbers by getting rid of zeros, and making math easier. It is a number notation which is the product of the number with the power of 10's. Exponential notation lets you move the decimal point in a number.




Hope that helps!!!! : )

Decimal: It’s easier to work with the numbers You can add, subtract, multiply and divide in your head (for the most part) instead of having to find common denominators and things like that.

Fraction: You can put repeating values in fraction form to represent them in a simpler way, as opposed to having to put the line over the repeating digits if it were in decimal form.

Power: Powers are just condensed forms of repeated multiplication, so they save space/time and you can use certain properties with some powers that allow you to multiply and divide them instantly.

Scientific notation: This is good when you’re dealing with numbers that have a lot of digits/place value. That can become confusing, so scientific notation is a way we can represent these numbers clearly and more condensed (takes less space/time).
