Answer:
5:7
Step-by-step explanation:
From the given graph it is clear that
The total number of circles = 12
The total number of patterned circles = 5
The total number of plain circles = 7
We need to find the ratio of patterned circles to plain circles.
[tex]Ratio=\frac{\text{patterned circles}}{\text{plain circles}}[/tex]
Substitute patterned circles = 5 and plain circles = 7 in the above formula.
[tex]Ratio=\frac{5}{7}[/tex]
[tex]Ratio=5:7[/tex]
Therefore, the ratio of patterned circles to plain circles is 5:7.
