Question

Jacoby followed a recipe that requires 2 cup for water four every 3 cups of flours. if he used 8 cups flours, how many cups of water did he use?

Answer 1

Answer:

5 and 1/3 cups of water.

Step-by-step explanation:

Set up a proportion like this:

  2:3 for the original recipe

Then a second proportion for the recipe Jacoby used:  

  w:8  (use w for the unknown water amount)

Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

  $\frac{2}{3} =\frac{w}{8}$

Use cross multiplication to get the new equation:

  8 x 2 (or 16) = 3w

Then, divide both sides by 3 to get the amount for w, or water, by itself:

5 and 1/3 = w

I hope this helps! ☺
