Wood beam drying

The raw wood beam weighs 85 kg. It is calculated that drying will reduce its weight in a ratio of 5:6. What will be its weight after drying?

Final Answer:

m₂ =  70.8333 kg

Step-by-step explanation:

$$\begin{gathered} m_1=85\text{kg} \\ {m}_2:m_1=5:6 \\ {m}_2=m_1\cdot \frac{5}{6}=85\cdot \frac{5}{6}=\frac{85\cdot 5}{6}=\frac{425}{6}=\frac{425}{6}\text{kg}=70.8333\text{kg} \end{gathered}$$
