(Answer) 54.2
The alien planet has unfamiliar names for substances and units of measures.
69 quibs of the substance called skwarnick has been obtained.
According to the units of measurement used in the alien planet,
14 quibs equal to 11 sleps
Therefore, 1 quib = [tex]\frac{11}{14}[/tex] sleps
Thus, 69 quibs of skvarnick = [tex]\frac{11}{14}[/tex] x 69 sleps = 54.2 sleps
For this reason, 69 quibs of the substance skvarnick in units of sleps is 54.2 sleps
