subtraction of rational number

Explanation:

time taken to mow 7 lawns last week $= \frac{7}{12}$ $= 7/12$
time taken to mow the lawns this week $= \frac{5}{12}$ $= 5/12$
time by which time taken last week is more than this week $= \frac{7}{12} - \frac{5}{12} = \frac{2}{12} = \frac{1}{6}$ $= 7/12-5/12= 2/12= 1/6$

$\frac{1}{6}$ $1/6$ of an hour
