Answer:
6.30
Step-by-step explanation:
19.20-13.30=6.30
Well, if you subtract 2 from 3 you will need to borrow from the next door and you will get 12. The 9 will turn to a 8 after you borrow 1 from it.
Then you subtract and get 9.
After that you subtract 8 and 3 and you will get 5.
Then the 1-1=0
So it is 5.90
You will need to convert 5.90 into time and you will get 6.30 since you subtracted .60,its a minute, from .90 and then it will be .30 You need to add the one in 5 and you will get 6.30
