GREETINGS!! (:

PART TO PART RATIO'S

1. - related to blue to related to green
- 3: 3
- 3 to 3
- rtb/ rtg = 3/3
- 1.0: 1
- 100 % :100
- Im not sure if theres an equivalent ratio for this one..

2. - 1 word to 2 or more words
- 1: 2
- 1 to 2
- word/ words = 1/2
- 0.5: 1
- 50% :100
- 1/2 = 12/24 ( I multiply the numerator and the denominator by twelve )

3. - vowels to consonants
- 43: 77
- 43 to 77
- v/ c = 43/ 77
- 0.55: 1
- 55.8 % :100
- 43/ 77 = 86/ 154 ( I multiply the numerator and the denominator by 2 )

PART TO WHOLE RATIO

1. - blue's to total
- 3: 12
- 3 to 12
- b's/ t = 3/12
- 0.25= 1
- 25% =100
- 3/12 = 1/4 ( I divided the numerator and the denominator by 3 )

2. - a to all vowels
- 6: 43
- 6 to 43
- a/ all vowels = 6/43
- 0.13= 1
- 13. 9 % = 100
- 6/43= 18/ 129 ( I multiply the numerator and the denominator by 3 )

- 4: 3
- 4 to 3
- gold, green's/ blue's = 4/3
-1.33 (continuous) : 1
- 133.3 % : 100
- 4/3 = 8/6 ( I multiply the numerator and the denominator by 2 )

2. - green's , silver to total
- 4: 12
- 4 to 12
- green's, silver/ total = 4/12
- 0.33 ( continuous ) : 1
- 33.3 % : 100
- 4/12 = 1/3 ( I divide the numerator and the denominator by 4 )

QUESTIONS:

1. Fractions,decimals and percents are like a chain. Tell me why or why not? Explain and show your answer.

2. How do you make a fraction for a three part ratio?

3. If you were ask to make another part to part ratio about this picture besides for the one I have, what would it be? Tell me the ratio notation, fraction, decimal, percent and its equivallent ratio.

THANKS FOR READING MY POST! GOOD LUCK FOR THE TEST TOMORROW!! HOPE YOU'LL DO GOOD!! (:
AND DONT FORGET TO COMMENT!! (:

Byeee!! (:

This is my bob for extra marks. I almost failed my test so that I need to work on some stuff. Like when to use a ratio table, I have no idea when to use a ratio table ( that's embarrassing ). Like the last question.

18) In a student election Carol gets 60% of the votes. If there were 485 votes cast, how many votes did Carol get?
My answer is 194 instead of 291. When I was doing the test, I have no clue what to do until when we went over it in class. I didn't know that we have to use a ratio table to show our work. What I did was I used a calculator. I kinda guess.

The other mistakes I got is kind of like the same thing as the one above because they all use ratio table to find the answers..

Question:
1. How do you know when to use a ratio table?

Good job Abby.
1. Fractions can be divided to make decimals. decimals can be multiplied to make percent.
2.iunno It'd be nice if u could explain that on a comment.
3.silver to total 1:12 1/12 0.08 8% 2:24

GOOD JOB ABBY!

1.) well a fraction is made by the ratio notation (i think),soo then to make a decimal jus divide the numerator and the denominator of the fraction, then to get the percent get the decimal and multiply it by 100.

2.) uhh... for this question i dont kno . maybe you cant make a fraction for a three term ratio but if it can be done on a two term ratio i could work on a three term ratio.

3.)uhh... im not sure if im right.
turquoise blue to total 1:12 1/12 0.08 8% .

1.When the question has anything to do with complicated percentages.
