370 papers need gradeed only 80% of them get done. How many ungraded papers will remain to be completed?
Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
multiply 370 by 0.8 (80% = 0.8)
subtract that result from 370
What do you get?
a quicker way to do is multiplying 370 by .20 (20% of the paper needed not to be graded)
To determine the number of ungraded papers that will remain to be completed, we first need to find out how many papers are graded. Given that 80% of the papers are done, we can calculate it as follows:
Number of graded papers = 80/100 * 370
Now, let's calculate it:
Number of graded papers = 0.8 * 370
Number of graded papers = 296
To find the number of ungraded papers, we subtract the number of graded papers from the total number of papers.
Number of ungraded papers = Total number of papers - Number of graded papers
Number of ungraded papers = 370 - 296
Number of ungraded papers = 74
Therefore, there will be 74 ungraded papers remaining to be completed.
