Nut mix weight

Mom bought a mixture of nuts. It contains 0.2 kg of hazelnuts. 1/4 kg of cashew nuts and 2/3 kg of peanuts. How much did the whole mix weigh?

Final Answer:

m =  67/60 = 1 ⁷⁄₆₀ kg

Step-by-step explanation:

$$\begin{gathered} a=0.2\text{kg} \\ b=1/4=\frac{1}{4}=0.25\text{kg} \\ c=2/3=\frac{2}{3}\doteq 0.6667\text{kg} \\ m=a+b+c=0.2+0.25+0.6667=\frac{67}{60}\text{kg}=1.1167\text{kg} \end{gathered}$$
