Question

A chemistry book comprises of two section:organic and non-organic in the ratio 2:8.
How much of each type of content will be needed to make a book of 400 pages?

Answer 1

Answer:

you will need 4 chapters of non-organic and approximately 6 chapters of organic chemistry

Answer 2

The ratio can always be written as 1/4. This means that for every one page of the organic section their will be 4 pages in the non-organic section.

We can write this equation as:

2x + 8x = 400

10x = 400

10x/10 = 400/10

x = 40

Now, we can multiply 40 to the original ratio.

2*40:8*40 → 80:320

Thus, their will be 80 organic pages and 320 non-organic pages.
