Why are the solutions to the proportions 50/x=10/20 and 10/50=20/x the same?

a. because both result in the equation 20x=500, which simplifies to x = 25

b. because both result in the equation 20x=500, which simplifies to X= 250

c. because both result in the equation 10x= 1,000, which simplifies to x= 10

d. because both result in the equation 10x= 1,000, which simplifies to X=100
