To find the part-to-whole ratio for yellow shoes, you first need to know the number of students who chose yellow and the total number of students.
In this case:
- Number of students who want yellow shoes: 16
- Total number of students: 60
The part-to-whole ratio for yellow can be written as:
16 (yellow shoes) : 60 (total students)
To simplify this ratio, divide both numbers by their greatest common divisor, which is 4:
16 ÷ 4 = 4
60 ÷ 4 = 15
Thus, the simplified part-to-whole ratio for yellow shoes is:
4 : 15
