tom has read 3/8 of the 480 pages in the book. how many pages are left to read? what is the ratio of pages read to pages not yet read?
please help! due tomorrow
(3/8) * 480 = ?
To find the number of pages that Tom has left to read, we first need to determine how many pages he has already read.
Tom has read 3/8 of the book, which means he has read (3/8) x 480 = 180 pages.
To find the number of pages left to read, we subtract the pages already read from the total number of pages:
Total pages - Pages already read = Pages left to read
480 - 180 = 300
Therefore, Tom has 300 pages left to read.
To find the ratio of pages read to pages not yet read, we need to compare the number of pages read to the number of pages left to read.
The ratio is defined as the amount of one quantity relative to another. In this case, the ratio can be expressed as:
Pages read : Pages not yet read
Since we have determined that Tom has read 180 pages and has 300 pages left to read, the ratio is:
180 : 300
This ratio can be simplified by dividing both numbers by their greatest common divisor, which is 60 in this case:
3 : 5
Therefore, the ratio of pages read to pages not yet read is 3:5.
