How to convert improper fractions to standard fractions?

The conversion is made according to the following formula:

[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]

In this problem, the time had to be faster than [tex]12\frac{2}{5}[/tex] minutes, which is a time in minutes of:

[tex]12\frac{2}{5} = 12 + \frac{2}{5} = 12 + 0.4 = 12.4[/tex]

Researching the problem on the internet, it is found that their time was of [tex]11\frac{3}{5}[/tex] minutes, hence:

[tex]11 + \frac{3}{5} = 11 + \frac{3}{5} = 11 + 0.6 = 11.6[/tex]

11.6 < 12.4, hence they broke the record.

12.4 - 11.6 = 0.8, hence they were 0.8 minutes faster.
