Jerick873 BOB Ratio

This is my Bob blog for extra marks .

First I must make 3 part-to-part ratios :

a) green to yellow - 7:5

b) blue to red - 2:10, 1:5

c) green to red- 7:10

Next I must make 2 part-total ratios:

a) green to total - 7:24

b) red to total - 10:24

Now I must make 2 part-to-part-to-part ratios:

a) yellow to blue to green - 5:2:7

b) red to green to total- 10:7:24

Here is my ratio expressed in ratio notation, fraction, decimal, percent, and word form

2:10(1:5) , 1/5, 0.2 , 20%, blue to red. To do this , when the ratio is in a fraction you divide the two numbers and you get the decimal form and to get to the percentage form you multiply the decimal by 100 because percents are out of 100

Here is where I show how to create equivalent ratio

blue to red 2:10, 4:20, 6:30, 8:40, 10:50 . To make equivalent ratios , what you got to keep in mind is , Whatever you do to one side you have to do to the other , so 2:10 is equivalent to 1:5 ... so you divide the 2 by 2 and since you did that to one side you have to do it to the other so 10 divided by 2 is 5 so 1:5.

Here are my 3 questions

1. What is the ratio of yellow to red?

2. What is an equivalent ratio to 2:24 (blue to total)

3. Show 2:4 as a fraction , decimal and percent.

BONUS QUESTION

1. Do you like M&Ms?

THANKYOU FOR READING THIS POST

p.s. you dont have to answer the bonus question it was just for fun :D and the other blue is on the left side squished in with between 2 reds and one green

Part 2 Bob 2

Well part is about my test , to be honest im kind of proud of my mark but i know there is still room for improvement .

Well my mistakes on my test mostly had to do with simplifying. Example

18:27 , i put 6:9 and it said to express in lowest terms but i didn't put it in lowest terms , but the answer would of been 2:3.

and there was another one about the cards in the deck. red cards to whole deck and i answered 2:4 , i forgot to simplify and 1:2 was there. But in my defense it did not say express lowest terms but I guess it was my fault cause we always have to simplify.
