Question

What is the answer to the recipe says she needs 480 grams of pasta for 4 people. how many kilograms will she need for 14?

Answer 1

Use a proprtion to solve:$\frac{480 grams}{4 people} = \frac{x}{14 people}$
Cross Multiply:                 480 · 14 = 4 · x
Divide both sides by 4: $\frac{480 x 14}{4} = x$
                                             1680 = x

Answer: she will need 1680 grams
