each of the variables a, b, c, d, e and f represents a different positive real number. given the equations below, which variable must have the greatest value: a, b, c, d, or e? a. 1.31 a = f b. 1.12b=f c. 1.01c=f d. 0.98d=f e. 0.31e = f

The greatest value is "e"

Step-by-step explanation:

We have the following equations:

a. 1.31 a = f

b. 1.12b=f

c. 1.01c=f

d. 0.98d=f

e. 0.31e = f

Then solving for "a", "b", "c", "d" and "e" we have:

a. a = f / 1.31

b. b=f/1.12

c. c=f / 1.01

d. d=f / 0.98

e. e=f / 0.31

Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.

The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.
