Why are the solutions to the proportions 40/80 = to x/10 and x/40= 10/8 the same

In 2 expression the value of x  is different

Step-by-step explanation:

It is given that,

40/80 = to x/10 and x/40= 10/8

To find the value of 40/80 = to x/10

40/80 = x/10

x = (40*10)/80

x = 5

To find the value of x/40= 10/8

x/40 = 10/8

x = (40*10)/8

x = 50

From the given results we get the value of x is different.

the answer is 15% decrease
