My three questions :
1.
Why is word ratio important here ?
2. How do you simplify red to total ?
3.
What would the ratio, fraction, decimal and percent be for green to orange?

1.Word ratio is important here because some colours have the same amount as eachother.
Example: There are 4 Yellow, Purple and Orange circles in this picture.
2.Red to total is 16:36.
To simplify that, divide red and the total by 2.
16÷2=8
36÷2=18
16:36 simplified is 8:18
3.word ratio- Orange:Green
ratio notation- 4:6
fraction- 6/4
decimal- 0.66
precent- 66.66%
