How do i round up one number ow do i round up one numder

Well, when your rounding by ones, if the ones place is lower than 5,  round lower. Like for example, 4 is lower than 5. So if you have 5,784, you have to round that 4 down to a 0. So it would be 5,780.

if it's higher that 5, like 7, you round up. Like for example, 507, you round it to 10, so 510.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
