wored 12.5hours 2nd painter 8 hours and 45 miniutes third painter 16.25 hours many total hours

Answer 1

To calculate the total hours worked by the three painters, you can add their hours together.

1. First painter: 12.5 hours
2. Second painter: 8 hours and 45 minutes (which is 8.75 hours, since 45 minutes is 0.75 of an hour)
3. Third painter: 16.25 hours

Now, let's add them up:

\[ 12.5 + 8.75 + 16.25 \]

Calculating this step by step:

1. \(12.5 + 8.75 = 21.25\)
2. \(21.25 + 16.25 = 37.5\)

So, the total hours worked by all three painters is 37.5 hours.
