If Sarah had 65 assignments to complete and she had 13 left to do, what percent is she finished? What percent is she not finished?

1 answer

To find the percentage of assignments Sarah has completed, divide the number of assignments she has completed by the total number of assignments and multiply by 100:

Percentage completed = (assignments completed / total assignments) * 100

Sarah has completed 65 - 13 = <<65-13=52>>52 assignments.

Percentage completed = (52 / 65) * 100 = 80%

Therefore, Sarah is 80% finished.

To find the percentage of assignments Sarah has not finished, subtract the percentage completed from 100%:

Percentage not completed = 100% - Percentage completed

Percentage not completed = 100% - 80% = 20%

Therefore, Sarah is 20% not finished.
