Math homework

It took Jose two-thirds of an hour to complete his math homework on Monday, three-fourths of an hour on Tuesday, and two-fifths of an hour on Wednesday. How many hours did it take Jose to complete his homework altogether?

Result

t = 1:49 h

Step-by-step explanation:

$t=\frac{2}{3}+\frac{3}{4}+\frac{2}{5}=\frac{40}{60}+\frac{45}{60}+\frac{24}{60}=\frac{40+45+24}{60}=\frac{109}{60}=1.81667=1:49\text{h}$
