A cookie recipe calls for 2/3 of a cup of flour and makes 2 dozen cookies. If you plan to make 8 dozen cookies, how many cups of flour do you need

Respuesta :

8/12 cups of flour. or 2/3 cups of flour

Answer:

2 and 2/3 of a cup of flour is needed to make 8 dozen cookies.

Step-by-step explanation:

It is given that a cookie recipe calls for 2/3 of a cup of flour and makes 2 dozen cookies.

The ratio of flour and cookies in dozen is

[tex]\frac{Flour}{Cookies}=\frac{\frac{2}{3}}{2}=\frac{1}{3}[/tex]       ..... (1)

Let x cup of flour needed to make 8 dozen cookies. The ratio of flour and cookies in dozen is

[tex]\frac{Flour}{Cookies}=\frac{x}{8}[/tex]         ... (2)

Equate ratio (1) and (2),

[tex]\frac{1}{3}=\frac{x}{8}[/tex]

Multiply 8 on both sides.

[tex]\frac{8}{3}=x[/tex]

[tex]2\frac{2}{3}=x[/tex]

Therefore 2 and 2/3 of a cup of flour is needed to make 8 dozen cookies.
