The recipe calls for 1/2 teaspoon of red pepper flakes for every 1 1/4 teaspoons of black pepper. How many teaspoons of red pepper will you need if you see only one teaspoon of black pepper?

Answer:you will need 2/5 teaspoons of red pepper

Step-by-step explanation:

The recipe calls for 1/2 teaspoon of red pepper flakes for every 1 1/4 teaspoons of black pepper.

Let the number of teaspoons of red pepper that you will need if you see only one teaspoon of black pepper be x. Therefore

If 1/2 teaspoon of red requires 5/4 teaspoon of black

x teaspoon of red will require 1 teaspoon of back pepper

Cross multiplying

1 * 1/2 = x * 5/4

5x = 4*1/2 = 2

x = 2/5
