If Jo is supposed to read one-half of a 100-page book for an English assignment and she has finished 38 pages, what percent of the assignment does she have left to do?
Please answer and explain.
Actually, the problem states that Jo has to read 1/2 of a 100 page book. It also asks what percent of the assignment is left. So:
38/50 x 100 = 76% read.
100 - 76 = 24% left to read.
100 - 38 = 62
62/100 = 0.62 = 62%
To find out what percent of the assignment Jo has left to do, we need to calculate the portion of the book she has already read.
Jo is supposed to read one-half of a 100-page book, which means she needs to read 100/2 = 50 pages.
Since Jo has already finished 38 pages, we can subtract this from the total number of pages she needs to read: 50 - 38 = 12 pages.
To express this as a percentage, we can calculate the ratio of the pages Jo has left to the total number of pages she needs to read, and then multiply by 100.
So, (12 / 50) * 100 = 24%.
Therefore, Jo has 24% of the assignment left to do.
To find out what percent of the assignment Jo has left to do, we need to determine how many pages she has left to read and then calculate that as a percentage of the total number of pages.
First, let's find out how many pages Jo has left to read.
Since Jo is supposed to read one-half of a 100-page book, she needs to read (1/2) * 100 = 50 pages in total.
Given that she has already finished 38 pages, we can subtract that from the total to find out how many pages she has left: 50 - 38 = 12 pages.
Now that we know that she has 12 pages left, we can calculate the percentage. To do this, we divide the number of pages left by the total number of pages and multiply the result by 100 to get the percentage.
So, Jo has (12 / 100) * 100 = 12% of the assignment left to do.
Therefore, Jo has 12% of the assignment left to do.
