To help Albie compare the ratio of students in her class who are wearing the color green, we can follow these steps:
-
Count the Total Number of Students: First, Albie needs to know the total number of students in her class.
-
Count the Number of Students Wearing Green: Next, she should count how many students are wearing green.
-
Calculate the Ratio: The ratio can be expressed as a fraction:
\[ \text{Ratio of students wearing green} = \frac{\text{Number of students wearing green}}{\text{Total number of students}} \]
-
Simplify the Ratio: If possible, the ratio should be simplified to its lowest terms.
-
Expressing as a Percentage (optional): If Albie wants to express the ratio as a percentage, she can multiply the decimal form of the ratio by 100.
For example, if there are 20 students in total and 5 of them are wearing green, the ratio would be:
\[ \frac{5}{20} = \frac{1}{4} \]
And as a percentage:
\[ \left(\frac{5}{20}\right) \times 100 = 25% \]
If Albie provides specific numbers, I can help her with the calculations!
