Question

You have used 2L of milk to prepare chocolate milk for 5 people. If you want to prepare chocolate milk for 10 people insted of 5, how much milk will you need for?

Answer 1

Respuesta:

4L

Explicación:

If 2L -----------> 5 people

  X   -----------> 10 people

If we apply "rule of 3", we multiply 10 times 2, supress repeated "people" and divide the result by 5.

10 people x 2L                20L        

---------------------- =          --------- =     4L

    5 people                      5

Hope it helps :)
