thank u
To find the total number of pages in Paula's book, we can set up a proportion using the percentage of pages she read and the total number of pages in the book.
Let x represent the total number of pages in Paula's book.
We can set up the proportion:
70% (percentage she read) = 85 pages (number of pages she read)
100% (total number of pages in the book) = x pages (total number of pages in the book)
Now, we can solve for x. We can cross multiply:
70% * x = 100% * 85
To solve for x, we can convert the percentages to decimals:
0.7x = 0.85 * 100
Simplifying,
0.7x = 85
Now, to isolate x, we can divide both sides of the equation by 0.7:
x = 85 / 0.7
Calculating,
x = 121.43
Therefore, the total number of pages in Paula's book is approximately 121.43 pages.
