Answer:
2:5
Step-by-step explanation:
Because if we look 8:20 can be turned into 8/20 and if we simply we got 2/5 and turn it into 2:5
To find the simplest ratio, you can take them in fraction and cancel of as many factors as you can.
The simplest ratio of numbers of circles to total shapes is 2:7
Simplest ratio of number of circles to total shapes.
If we cannot take out any common factor from both parts of ratio(except 1), then that form is simplest form. Example: 5:7 is in simplest form since there is no common factor of 5 and 7 except 1.
Total shapes' count = count of circles + count of triangles = 8+20 = 28
[tex]\dfrac{\text{Total circles}}{\text{Total shapes}} = \dfrac{8}{28} = \dfrac{4}{14} = \dfrac{2}{7}[/tex]
Thus, the needed ratio is 2:7.
