Raquel's Bob & Ratio

PART TO PART RATIO:
Green:Blue 6:1
Blue:Red 1:10
Yellow:Blue 6:1

PART TO WHOLE RATIO:
Red:Total 10:23
Blue:Total1:23

3 PART RATIO:
Green:Blue:Yellow 6:1:6
Total:Letters:Green 23:7:6

Here is the ratio that I picked to show a ratio notation, fraction, decimal, percent. Blue:Red. Here is how I did it:
Ratio Notation: 1:10
Fraction:1/10
Decimal: 0.10
Percent:10%
I got the fraction by adding up the numbers of blue m&m's and red m&m's. I got the decimal by dividing the fraction and I got the percent by multiplying the decimal by 100.

Making An Equivalent Ratios
blue to red, 1:10 2:20 3:30 4:40 5:50. These are all equivalent fractions. When your trying to make an equivalent fraction you have to know that if you do something to one side you do it to the other. So, 1:10 is equivalent to 2:20 because you multiplied 1 by 2 and so what you do on one side you do it on the other by doing that 10 times 2 equals 20. So the ratio is 2:20.

3 QUESTIONS
1: If you make a ratio of blue:total. What would be the fraction decimal and the percentage be and How did you do it?
2: What would the equivalent ratio look like if it was 6:1?
3: What if there was 3 more blue then red? What would the fraction decimal and percentage look like?

THANKS FOR READING
(P.s The ratios might be wrong cause I may have miss counted it. )
Anyways. Byeeeeeeeeeee.
:D

PART 2

What were the mistakes you made on your test. Show examples of answers that were wrong. What was your mistake. How will you remember what to do in future tests?

- Some of the mistakes I did on my test was that I didn't read the question carefully. I forgot to simplify my work cause I forgot to. I also didn't show my work so that's why I did bad on my test. I also need to write on my paper on showing how I got the answer. The next time I do a test, I will study more harder so that I know what to do. I will also try my hardest to read the question carefully and show how I did it using ratio tables etc.

RE-WRITE 2 QUESTIONS THAT GAVE YOU DIFFICULTY WITH DIFFERENT NUMBERS.
