Three-quarters 5783

A crane loads goods onto the wagons of a freight train. Goods of the first type weigh two and three-quarter tons, goods of the second type two and a quarter tons, goods of the third type one and a half tons, goods of the fourth type three-quarters of a ton. What is the weight of the goods loaded on the wagon?

Final Answer:

x =  7.25 t

Step-by-step explanation:

$$\begin{gathered} a=2+3/4=\frac{11}{4}=2.75\text{t} \\ b=2+1/4=\frac{9}{4}=2.25\text{t} \\ c=1+1/2=\frac{3}{2}=1.5\text{t} \\ d=3/4=\frac{3}{4}=0.75\text{t} \\ x=a+b+c+d=2.75+2.25+1.5+0.75=\frac{29}{4}\text{t}=7.25\text{t} \end{gathered}$$
