The question is an illustration of proportion
App 1 uses 5/12 more of the storage space of the phone than app 2
The proportions are given as:
App 1 = 1/1
App 2 = 5/12
The difference (d) is then calculated as:
d = App 1 - App 2
So, we have:
[tex]d = \frac 11 - \frac 5{12}[/tex]
Take the LCM
[tex]d = \frac {12 - 5}{12}[/tex]
[tex]d = \frac {7}{12}[/tex]
This means that:
App 1 uses 5/12 more of the storage space of the phone than app 2
