Today Mr.Harbeck told us to create ratios on the picture we use and comment on them in our comments section.

**Pt. 1**

Harbeck told us to use...

1)Part to Part-

*2 term ratio*

2)Part to Whole-

*2 term ratio*

3)Part to Part to Part-

*3 term ratio*

4)Part, Part, Part to whole-

*2 term ratio*

To create ratios.

1) greens to blues

3 : 3

2) greens to whole

3 : 12

3) gold to greens to blues

1 : 3 : 3

4) greens, blues, orange to total

3 , 3 , 1 : 12

**Pt. 2**

Harbeck also told us to create questions about the ratios and

*answer them in the comment box*.

1) What type of ratio terms are the numbers 1, 2, 3 and 4.

2) Give an example of an equivalent fraction.

3) Give an example of a simplified fraction.

*Don't forget to study for the ratio test on Wednesday. Don't forget to study the numbers Harbeck gave us in the homework book.*___________________________________________________________________

Hey guys,

Harbeck told us to make a scribepost on the test.

1)

**What were the mistakes you made on your test?**

Some of the mistakes I made on the test were Question #18.

The question was...

In a student election Carol gets 60% of the voted. If there were 485 votes cast, how many votes did carol get.

My answer was this.

289/485=(0.595)876288

0.595 x 100=59.5

59.(5)rounded up=60

**carol got 289 votes**

My mistake was forgetting to use a table ratio.

I will remeber that when you get a percentage question you should use a

**ratio table.**

**2)Write 2 questions that gave you difficulty on the test answer them in your comments section.**

Question # 8

A picture frame has a width to length ratio of 5:7. If the width of the photo is 9cm, the length of the photo is

a)11 cm b)12.6 cm c)14 cm d)16 cm

Question # 7

A rapid transit train has 39 passengers on it as it starts it's run. At the first stop 12 passengers get off and 18 passengers get on.

**Please leave a comment on the questions.**

QUESTION 1.

ReplyDelete1 is a part to part ratio term(2 term ratio)

2 is a part to whole ratio term(2 term ratio)

3 is a part to part to part ratio term(3 term ratio)

4 is a part, part, part to whole ratio term(2 term ratio)

QUESTION 2

an equivalent fraction can be

2/3=4/6 I multiplied each number in the first fraction by 2. what you do to one side you do to the other.

QUESTION 3

a simplified fraction can be

6/12=2/4 I divided each number in the first fraction by 3. what you do to one side you do to the other.

Q1

ReplyDelete1 is part-to-part ratio.

2 is part-to-whole ratio.

3 three term ratio.

4 two term ratio.

Q2

before:

blue to pink (3:2)

after

blue to pink (9:6)

what i did is i multiplied 3 by 3 to get 9 then i also multiplied 2 by 3 to get 6.because what ever you did to the the 1st side you have to do the same thing to the other

Q3

before

2:12 (pink to total)

after

1:6

because i divided 2 by 2 which equals to 1 then i also divided 12 by 2 which equals to 6.

if you divide the 1st side by 2 you have to do the same thing to the other side

------------------------------------------------

good job your post is very easy to understand

1) Part to Part Ratio

ReplyDelete2) 2/3 - 4/6

3) 8/16 - 1/2

Good job Bruce! :)

1.a) part-to-part ratio

ReplyDeleteb) part-to-whole ratio

c) three term ratio

d) two term ratio

2. gold to green - 1:3 - 2:6

3.yellow to total - 2:12 - 1:6

1)I don't really get what your asking

ReplyDelete2)2/4 = 1/2

3)14/12 = 7/6
