Question

Which fraction and equivalent decimal correctly shows the ratio of shaded circles to all circles?

Answer 1

Shaded circles = 4
Total circles = 12


`(shaded~circles)/(total~circles)` =
`(4)/(12)`


`(4)/(12)` as a simplified expression =
`(2)/(6)`
We can simplify it even more =
`(1)/(3)`

Fraction =
`(1)/(3)`

Equivalent decimal = 1 ÷ 3 = 0.33
