Nutballs

The dough for nutballs contains, among other things, two basic raw materials: flour and nuts, in a ratio of 2:1. How much flour is needed, and how many nuts are needed for 1 kg of dough if the "other" is 100g?

Correct answer:

m =  600 g
o =  300 g

Step-by-step explanation:

$$\begin{gathered} m_1=1\text{kg}\to \text{g}=1\cdot 1000\text{g}=1000\text{g} \\ {m}_2=100\text{g} \\ {m}_3=m_1-m_2=1000-100=900\text{g} \\ m=\frac{2}{2+1}\cdot m_3=\frac{2}{2+1}\cdot 900=600\text{g} \end{gathered}$$

$o=\frac{1}{2+1}\cdot m_3=\frac{1}{2+1}\cdot 900=300\text{g}$
