Just draw a simple picture of a house or a dog or a person or a building where you have only 3 rectangles and 1 circle, 6 rectangles and 2 circles, 9 and 3, etc. Do this three times and you should be set.
Let
x--------> the number of rectangles in the drawing
y--------> the number of circles in the drawing
r--------> ratio of rectangles to circles
we know that
r = y x
r = 1 3
Drawing N 1
see the attached figure N 1
we have
the number of rectangles is equal to 3
x = 3
the number of circles is equal to 1
y = 1
Find the ratio
r = 1 3
Drawing N 2
see the attached figure N 2
we have
the number of rectangles is equal to 6
x = 6
the number of circles is equal to 2
y = 2
Find the ratio
r = 2 6 = 1 3
Drawing N 3
see the attached figure N 3
we have
the number of rectangles is equal to 9
x = 9
the number of circles is equal to 3
y = 3
Find the ratio
r = 3 9 = 1 3
To illustrate the ratio of rectangles to circles as 3:1, we can create three drawings: one with 3 rectangles and 1 circle, another with 6 rectangles and 2 circles, and a third with 9 rectangles and 3 circles. Each drawing maintains the same ratio. These examples clearly demonstrate the required ratio in varied quantities.
