Calculating the Ratio of Yellow to Green Pencils

To calculate the ratio of yellow to green pencils, we can use the information provided. The number of yellow pencils is 7, and the number of green pencils is 2.

The ratio of yellow to green pencils is calculated by dividing the number of yellow pencils by the number of green pencils.

Ratio of yellow to green pencils: 7 / 2 = 3.5

Determining the Difference in Quantity and the Proportion of Green Pencils

Now, let's determine the difference in quantity between yellow and green pencils and the proportion of green pencils in the total.

Difference in quantity: The difference in quantity between yellow and green pencils is 7 - 2 = 5.

Proportion of green pencils: To find the proportion of green pencils in the total, we can use the total number of pencils, which is the sum of yellow and green pencils (7 + 2 = 9). The proportion of green pencils is then calculated by dividing the number of green pencils by the total number of pencils.

Proportion of green pencils: 2 / 9 ≈ 0.2222 (rounded to four decimal places)

So, the proportion of green pencils in the total is approximately 0.2222 or 22.22%.

Conclusion

In conclusion, the ratio of yellow to green pencils is 3.5:1, meaning there are 3.5 times as many yellow pencils as green pencils. Additionally, green pencils make up approximately 22.22% of all the pencils.
