Step-by-step explanation:

__________________________________________

Start at:

____________________

6:00 a.m.

____________________

Add 1  1/4 hours ; which is

1 + (1/4) hours:

Note:  " 1 hr = 60 min." .

_____________________

So:

 (1/4 hr) *  () ;

                                       =  (1/4) * 60 min;

                                       = (60/4) min.

                                       = 15 min.

______________________

So:  1  1/4 hr =  1 hr. 15 min.;

______________________

So:  Start at:  6:00 a.m .

Add  " 1  1/4 hrs."  ;  i.e. add 1 hr 15 min.

_______________________

6:00 a.m + 1 hr = 7:00 a.m.  ;

 7:00 a.m.  +  15 min. =  7: 15 a.m. ;

_______________________

Now, we are at:

_______________________

7:15 a.m.  ;

Now add:  "1/2 hour" to "7:15 a.m." to this time.

Note:  " 1 hr = 60 min.

So;

"1/2 hr = (1/2) * (60 min) = (60 / 2) min. = 30 min.

________________________

So: we have 7:15 a.m. ;

we add "30 min." to this time.

and we have:  7:45 a.m.

___________________________________________________

The answer is:  " 7:45 a.m. "  .
