Rica Caught Fish That Weighed 578 Lb 105 Lb And 863 Lb What Was The Total Weight Of All Fish That Rica Caught In Kg Assume 1 Lb 454g class=

Sagot :

The weight of the fish caught are

[tex]5.78lb,10.5lb,8.63lb[/tex]

We are given that

[tex]1lb=454g[/tex]

But

[tex]454g=0.454\operatorname{kg}[/tex]

Hence

[tex]1\text{ lb}=0.454\operatorname{kg}[/tex]

Therefore

[tex]\begin{gathered} 5.78\text{ lb}=5.78\times0.454\operatorname{kg}=2.62412\operatorname{kg} \\ 10.5\text{ lb}=10.5\times0.454\operatorname{kg}=4.767\operatorname{kg} \\ 8.63\text{ lb}=8.63\times0.454\operatorname{kg}=3.91802\operatorname{kg} \end{gathered}[/tex]

Hence, the total weigh in kg will be

[tex]2.62412kg+4.767\operatorname{kg}+3.91802\operatorname{kg}=11.30914\operatorname{kg}[/tex]

Therefore, the total weight of all fish that Rica caught, in kg is 11.30914kg
