Answer:
1:3
Proof:
The ratio of circles to the total shapes is 1:3.
What is a ratio ?
A ratio is a mathematical way of comparing how many parts is occupied by a thing to an another thing or to the total part.
a:b = c:d, can be written as a/b = c/d which is ad = bc.
According to the given question there are 6 triangles and 3 circles.So total number of shapes including triangles and circles are ( 6 + 3 ) = 9.
So, the ratio of total shapes to the circles is
= No. of circles ÷ Total no. of shapes
= 3/9.
= 1/3.
