If a recipe requires 400 grams of potatoes for four people, how many kilograms would be required for 12 people?

1.2 kg

Step-by-step explanation:

We need 400 grams of potatoes for 4 people. That means each person will require 400 / 4 = 100 grams.

Now, we have 12 people, so the total number of grams needed will be:

(100 g/person) * (12 people) = 1200 grams

However, we want the answer in kilograms. There are 1000 grams in a kilogram, so divide 1200 by 1000:

1200 / 1000 = 1.2 kg

The answer is 1.2 kg.

1200g or 1.2 kg

Step-by-step explanation:

We know that you need 400 grams of potatoes for 4 people to make a recipe and we want to find out how many for 12 people so

Method 1

First of all we would need to work out the amount needed for 1 person so,

400g = 4 people

? g     = 1 person

4 ÷ 1 = 4

400 ÷ 4 = 100

So 100g is needed for one person using that information

1 person = 100g

12 people = ? g

1 × 12 = 12

100 × 12 = 1200 g

Method 2

We can see that we need 400g for 4 people and we want to find out the amount for 12 people so

400g = 4 people

?g      = 12 people

12 ÷ 4 = 3

400 × 3 = 1200g

So you would 1200g or 1.2 kg of potatoes to make this recipe for 12 people
