How many minutes are there in 6 3/4 hours

405

Step-by-step explanation:

there are 60 min in a hour so you do 6*60 and you get 360

then 3/4 of an hour is 45 mins

so you add 360 and 45 and you get 405

405 minutes

Step-by-step explanation:

-well we all know that in one hour there is 60 minutes so in six hours there is going to be 360 minutes (you just multiply 60 by 6)

- and every quarter of an hour is 15 min so 3/4 would be 45 min (15 times 3)

- and then lastly all you have to do is add them up together 360 + 45 = 405min : D
