Final answer:
To find what percentage of the pears are yellow (6 out of 18), the number of yellow pears is divided by the total number of pears and then multiplied by 100, resulting in approximately 33.33%.
Step-by-step explanation:
The question '6 of 18 pears are yellow' is asking for the percentage of the whole that is a specific part - in this case, yellow pears. To find the percentage, we divide the number of yellow pears by the total number of pears and then multiply by 100 to convert the decimal to a percent. So, we calculate (6/18) × 100 to get the percentage of pears that are yellow.
Performing this calculation, (6/18) × 100 = 33.33%, which means that approximately 33.33% of the pears are yellow. This is a basic proportion calculation in mathematics where a part is compared to a whole to express it as a percentage.
