What is the ratio of blue shapes to all shapes in the set below?
2 blue triangles, 1 blue circle, and 2 blue squares. 1 orange square, 2 orange circles, and 1 orange triangle.
4:9
5:9
4:5
5:4

Step-by-step 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

therefore

The ratio is equal to

substitute

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
