4:9
5:9
4:5
5:4

Answer 1

Answer: It would be letter B (5:9)

Explanation:

Answer 2

`ratio=(5)/(9)`

Explanation:

Let

x ----> the number of blue shapes in the set

y ----> all shapes in the set

we know that

To find out the ratio of blue shapes to all shapes in the set , divide the number of blue shapes in the set by the number of all shapes in the set

we have

`x=5\\y=9`

therefore

The ratio is equal to

`ratio=(x)/(y)`

substitute

`ratio=(5)/(9)`
