Verified answer

Answer:

To find out how many hours the laborer worked on that day, you simply need to add the hours worked in the morning to the hours worked in the evening:

Morning hours worked: 19/6 hours

Evening hours worked: 19/4 hours

Now, add these two amounts:

(19/6) + (19/4)

To add these fractions, you need a common denominator, which is 12 in this case. So, you can convert both fractions to have a denominator of 12:

(19/6) can be converted to (38/12) because 6 goes into 12 twice.

(19/4) can be converted to (57/12) because 4 goes into 12 three times.

Now, add them:

(38/12) + (57/12) = (38 + 57)/12 = 95/12

So, the laborer worked 95/12 hours on that day, which is equivalent to 7 hours and 55 minutes.
