Two important ingredients for baking bread are yeast and flour. To make a loaf of
bread of at most 40 servings, maintain a yeast to flour ratio of 1:200. If you're making
a loaf of more than 40 servings, use a ratio of 1:180.
If you're making 40 servings of bread and using 0.35 oz of yeast, how many ounces of
flour do you need?
If you're making 90 servings of bread and using 360 oz of flour, how many ounces of
yeast do you need?

Respuesta :

Using proportions, it is found that:

  • 70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.
  • 180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.

What is a proportion?

A proportion is a fraction of total amount, and the measures are related using a rule of three.

For 40 servings:

  • 1 oz of yeast is equivalent to 200 oz of flour. How many oz of flour are needed for 0.35 oz of yeast?

The rule of three is:

1 oz yeast - 200 oz flour

0.35 oz yeast - x oz flour.

Applying cross multiplication:

[tex]x = 200(0.35) = 70[/tex]

70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.

For 90 servings:

  • 1 oz of yeast is equivalent to 180 oz of flour. How many oz of yeast are needed for 360 oz of flour?

The rule of three is:

1 oz yeast - 180 oz flour

x oz yeast - 360 oz flour.

Applying cross multiplication:

[tex]2x = 360[/tex]

[tex]x = \frac{360}{2}[/tex]

[tex]x = 180[/tex]

180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.
