Vance Randolph · Answer 1

She spent an hour and 18 minutes doing her homework

Step-by-step explanation:

1/2 + 4/5 = 1 3/8

half of an hour is 30 minutes

and 4/5 of an hour is?

you have to take 60 and divide it by 5 which equates to 12. So then you take 12 and multiply it by 4 which is 48. So if you add 30 and 48 it is 78 minutes. From here we can subtract 60 from from 78 in which you would get 18. There fore an hour and 18 minutes.
