Question

Daisy is cooking pasta. The recipe says she needs 480 grams of pasta for 4 people. How many kilograms will she need for 14?

Answer 1

pasta needed for 4 = 480gm
pasta needed for 1 = 480/4
= 120
pasta needed for 14 = 120*14= 1680gm

Answer 2

We will use simple unitary method to solve such a question, so now let us begin.

Given,

For 4 people, we need 480 g of pasta.

In terms of kilograms,

For 4 people, we need 480/1000 kg of pasta.
For 4 people, we need 0.48 kg of pasta.

Now,

For 1 person, we need 0.48/4 kg of pasta.
For 1 person, we need 0.12 kg of pasta.

Hence,
For 14 people, we need 0.12 * 14 kg of pasta.

For 14 people, we need 1.68 kg of pasta.

So your answer will surely be 1.68 kg and in terms of CGS unit(grams) your answer will be 1680 g.
