In a geography text book 35% of the pages are colored.if there are 98 colored pages,how many page are there in the whole book?

280

0.35x = 98

Solve for x.

To find the total number of pages in the whole book, we can set up a proportion using the given information:

35% of the pages = 98 colored pages

Let x represent the total number of pages in the book.

We can set up the proportion as:

35/100 = 98/x

To solve for x, we can cross multiply:

35x = 100 * 98

35x = 9800

Divide both sides of the equation by 35:

x = 9800/35

Simplifying the fraction gives:

x = 280

Therefore, there are 280 pages in the whole book.

To determine the total number of pages in the whole book, we need to find the percentage of colored pages and use that information to calculate the total number of pages.

1. Start by setting up a proportion to find the percentage of colored pages:
35% of the pages = 98 colored pages

2. Let's assume the total number of pages in the book is represented by the variable 'x'. Now we can set up the proportion:
(35/100) * x = 98

3. Solve for 'x' by cross-multiplying and then dividing:
(98 * 100) / 35 = x

Simplifying the calculation:
9800 / 35 = x
280 = x

Therefore, there are 280 pages in the whole book.
