To find the answer, we can set up a proportion using the number of pages and the number of days it takes Mary to read them.
If Mary read 105 pages in 5 days, we can set up the proportion:
105 pages / 5 days = 504 pages / x days
To solve for x, we can cross multiply:
105x = 504 * 5
105x = 2520
Dividing both sides by 105, we find:
x = 2520 / 105
x ≈ 24
Therefore, it will take Mary approximately 24 days to read a 504-page book.
To find out how long it will take Mary to read a 504-page book, we can set up a proportion using the number of pages and the number of days it took her to read the 105-page book.
The proportion is: (105 pages / 5 days) = (504 pages / x days)
To solve for x, we can cross-multiply:
105 * x = 5 * 504
Now let's solve for x:
105x = 2520
Divide both sides of the equation by 105:
x = 2520 / 105
Simplifying the equation, we get:
x = 24
Therefore, it will take Mary 24 days to read a 504-page book.
To find out how long it will take Mary to read a 504-page book, we can set up a proportion with the number of pages she reads in a certain number of days.
First, let's find out how many pages Mary reads in 1 day. We divide the number of pages (105) by the number of days (5) she took to read the book:
105 pages / 5 days = 21 pages per day
We can use this information to set up a proportion:
105 pages / 5 days = 504 pages / x days
To solve this proportion, we can cross-multiply:
105 * x = 5 * 504
Divide both sides of the equation by 105:
x = (5 * 504) / 105
Now, let's calculate that:
x = 2520 / 105 = 24
Therefore, it will take Mary 24 days to read a 504-page book. So the correct answer is:
24 days
