Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same?
because both result in the equation 20 x = 500, which simplifies to x = 25
because both result in the equation 20 x = 500, which simplifies to x = 250
because both result in the equation 10 x = 1,000, which simplifies to x = 10
because both result in the equation 10 x = 1,000, which simplifies to x = 100
