Examine the figures. What is the ratio of squares to triangles?

Orlov [11]

Answer:

Step-by-step explanation:

First, count how many squares there are: 8 squares.

Now, count how many triangles there are: 6 triangles.

Ratio is simply the number of one thing divided by the number of the other. Here, since we want the ratio of squares to triangles, we have:

8 squares / 6 squares

We can simplify this to:

8 / 6 = 4 / 3

And finally, this can be written in the "ratio notation":

4 / 3 = 4 : 3

The answer is B.
