How do you round off mixed numbers?

Answer 1

As in, 4½

Halfs and greater round up

Less than half round down

Just like with anything else.

When going from one fraction to a certain type of fraction you just go by how close it is to the next interval.

For example: 5¾ rounded to the nearest seventh would take some imagining

5¾ = 5 and 5.25/7 so you don't want that decimal in your fraction you round DOWN to the 5 because it is under half. Thus it is 5 and 5/7

And = denoting a decimal/fraction, 34.5 = 34 and 5

It seems unlikely you will be needing to know how to round mixed numbers anyways.
