Question

Your teacher asks you to find a recipe that includes two ingredients with a rate of 2 units over 3 units.

Answer 1

For cooking "The Great Cheesecake", a good chef need 2 kilos of flour and 3 kilos of cheese, more talent and a bunch of joy.

If you needed to triple the recipe, you'll need 6 kilos of flour and 9 kilos of cheese, but the rate wouldn't change because:

$\frac{6}{9} = \frac{2}{3}$
