Education - 5 modules

In a self-paced online class, there are five modules. The first four modules are worth the same, but the fifth module is worth as much as the other four combined. A student is one-fourth of the way through the last module and has done one-third of three of the other four. She has completed the first module entirely. What fraction has she completed on an average of each of the modules?

Correct answer:

x =  3/8

Step-by-step explanation:

$x=\frac{\frac{1}{4}\cdot 4+\frac{1}{3}\cdot 3+1}{4+4}=\frac{3}{8}=0.375$
