You are on an alien planet where the names for substances and the units of measures are very unfamiliar.
Harlamova29_29 [7]

Answer: 25.3


Explanation:


The question aks to convert 19 quibs, which is the amount of skvarnick that you obtained, to sleps.


Since, you are given the equivalence between sleps and quibs, you can build your own conversion factor, which is how the sciientific calculations are made:


  • equivalence: 4 sleps = 3 quibs
  • divide both sides by by 3 quibs: (4 sleps / 3 quibs) = (3 quibs / 3 quibs)
  • simplify: 4 sleps / 3 quibs = 1 ← conversion factor

Now, you can multiply 19 quibs by the conversion factor:


  • 19 quibs × 4 sleps / 3 quibs = 76 /  3 sleps ≈ 25.3 sleps.  ← answer

The quibs units cancel out since they are in the numerator and denominator, leaving only sleps.
