There are 2 squares and 4 triangles. What is the simplest ratio of
squares to total shapes?

1:3

Explanation:

There are 2 squares and 6 shapes total. Therefore the number of squares is 2 out of 6 shapes (2:6). That can be simplified by dividing by the least common denominator (2).

2/1=1

6/2=3

So 2:6 is the same as 1:3.

the answer is b. 300t + 3/2xt
