Rational Numbers

By: Connor Wallen and Tristan Reidell

Part 1: Our Numbers

1: 0.33

2: -5

3: 3

4: -1/2

Part 2.1: Comparing

1: 0.33 > -5

2: 0.33 < 3

3: 0.33 > -1/2

4: -5 > 3

5: -5 > -1/2

6: 3 > -1/2

Part 2.2: Ordering

-5, -1/2, 0.33, 3

Part 2.3: Number Line

-1/2 0.33

@-----l-----l-----l-----l--@--l--@---l-----l-----@

-5 0 3

Part 3: Absolute Value

1: [0.33]+[-5]=5.33

2: [-5]-[-1/2]=4 1/2=4.5

3: [3]x[-1/2]=1 1/2=1.5

4: [0.33]/[-5]=0.066

Part 4: Integer Operations

Addition:

1: -7+(-12)=-19

2: -10+20=10

Subtraction:

1: -7-(-20)=13

2: 33-(-42)=75

Multiplication:

1: 1.11 x 3=3.33

2: 20 x (-30)=-600

Division:

1: 20/2.5=8

2: - 9.99/3=333

Part 5: Real Life Problems

1: Jimmy had 17 chocolate bars. He divided them among himself and 3 of his friends. Afterwards, he bought 19 more. How many chocolate bars does Jimmy have in the end? 23.25

My tackk is going to show my views on a couple of math problems I did!

It has negative and positive numbers!

Enjoy! :)

.3-25-1/2
5 > -25 > .35 > -1/2-2< .3.3 > -1/2-1/2 > -2
My # line is in the pictures!
-1/2 = 1/25 = 5.3 = .3-2 = 2
5+.3=5.3
-1/2+-2=-2 1/25-.3=4.7
-2x5=-10
.3\5=160 (repeating)-1/2\-2=1.5
Word problems in pictures!
