Question

Bradley decides to include 5 pages of photographs for every 15 pages. Use equivalent ratios to find how many pages of photographs will be in a 150 page cookbook?
There are 25 pages for dessert recipes, 75 pages for meat recipes and 50 for veggie. recipes.

Solving for equivalent ratios.

Answer 1

Answer:

50 photographs

Step-by-step explanation:

$\frac{5}{15} = \frac{x}{150}$

Solve using cross multiplication.

15x = 750

x = 50

There will be 50 photographs in a 150 pages cookbook.

OR

You know that  $\frac{1}{3}$ of the pages are photos since 5 over 15 equals one third. Therefore, you can multiply 150 by $\frac{1}{3}$ to also get 50.
