Jacob had math homework on 81 evenings.

Step-by-step explanation:

Time spent of each evening = 1/3 of an hour

Time spent in minutes = $\frac{1}{3}*60 = 20\ minutes$

Total time spent = 27 hours

Total time spent in minutes = 27*60 = 1620 minutes

Let,

x be the number of evenings spent doing math homework.

Time spent each day* Number of evenings = Total time spent

$20x=1620$

Dividing both sides by 20

$\frac{20x}{20}=\frac{1620}{20}\\x=81$

Jacob had math homework on 81 evenings.
