Empty and full

An empty can has a mass of 1/6 lb. When it is filled with sand, it has a mass of 7/12 lb. Find the mass of the sand in the can?

Result

s =  0.417 lb

Solution:

s=712−16=512≐0.4167≐0.417 lbs=\dfrac{ 7 }{ 12 } -\dfrac{ 1 }{ 6 }=\dfrac{ 5 }{ 12 } \doteq 0.4167 \doteq 0.417 \ \text{lb}
