Fractions on the Calculator
Automating fractions
If you are planning to apply for the nursing program, do your
fraction problems by hand.
You will not be allowed to use a calculator on the nursing test,
so you need to be comfortable manipulating fractions.
If you are not going into a program that tests basic math skills
without a calculator, proceed with this lesson!
The Key to your Success!

Improper or Mixed?
Advanced math classes leave improper fractions.
They don’t change them to mixed numbers unless it
is a story problem that clearly requires a mixed
number answer.
If the question is How far did Sally jog today? We
would never say 669 miles.

1. If you know you will need to do basic math
by hand in the future, practice now!
2. If your future includes a calculator, make
sure you have a fraction key!
3.
Use your head to figure out the game plan.
4. Use your calculator for the grunt work.
