​Whole Number

• ​DEF counting numbers including zero

• ​Application: Good for describing real items

• ​What operators can we use? add, subtract, multiply, and divide

Integers

• ​DEF positive and negative numbers including zero

• ​Application: good for describing

  • Debt

  • ​Temperature

  • ​Above/Below Sea Level

​What are fractions?

• ​DEF fractions are numbers that describe a part of a whole. They include integers, whole numbers, and zero

​What are fractions

• ​Fractions belong in the number set called rationals --> "ratio" of two numbers

• ​Applications: they tell you what portion of a whole you need, have, or want.

• ​Real-life applications:

  • ​baking

  • ​splitting up food

  • ​decimals and percentages

​Fractions In a Nutshell

• ​Fractions are the division of two numbers

​

• ​The remainder part gets included in the number (For example, the remainder for is 0.25)

​History of Fractions

• ​Brahmagupta is responsible for the modern understanding of fractions like this

  2

  4

  • ​where 4 is how many pieces the whole is split up

  • ​where 2 is how many pieces out of the 4 were taken

• ​The Arabs came up with the bar when writing fractions

​Other Ways to Represent Fractions

• ​Percents --> per one-hundredth

• ​Decimals

​Finding The Decimal Form

1. ​long division

2. ​the numerator is the dividend

3. ​the denominator is the divisor

​Finding The Decimal Form 2/3

1. ​long division

2. ​the numerator is the dividend 2

3. ​the denominator is the divisor 3

​How to Find the Percent From a Decimal

​Improper Fractions

• ​​Def a fraction where the numerator is greater than the denominator

• ​great for computation

Mixed Number

• ​​Def a number where the whole part is the big number the fraction part how much is leftover

• ​a different form of an improper fraction

• ​great for final representation (after calculating, convert result this form)
