1) A family is planning a holiday dinner. They need to adjust a recipe that serves 8 people to serve 12 people. The original recipe calls for 3/4 cup of sugar, 2.5 cups of flour, and 1.5 teaspoons of salt. What are the new ingredient measurements?

Answer:

The new measurements are 1 1/8 cup of sugar, 3.75 cups of flour, and 2.25 teaspoons of salt.

Step-by-step explanation:

Use ratio and proportion

Sugar:

[tex] \frac{8}{12} = \frac{ \frac{3}{4} }{x} [/tex]

Cross multiply

8x = 12(3/4)

8x = 9

Divide both sides by 8

x = 9/8

or 1 1/8

Do the same for the other ingredients.

Flour:

[tex] \frac{8}{12} = \frac{2.5}{x} [/tex]

Cross Multiply

8x = 12(2.5)

8x = 30

Divide both sides by 8

x = 3.75

Salt

[tex] \frac{8}{12} = \frac{1.5}{x} [/tex]

Cross Multiply

8x = 12(1.5)

8x = 18

Divide both sides by 8

x = 2.25
