When You're Doing Fractions

When you're doing fractions:
Addition or subtractions

Denominators must be the same
If they're different
Then equivalent
Fractions must be your aim

When you multiply
This rule does not apply
Don't you know divide is the same
Once you convert it

When adding fractions
There are certain actions
That you need to implement
To do it right

You need to create a
Common denominator
If the bits that you're given are a different size

This you have to do
For plus and minus too
But not when you times or divide

Cause when you're doing fractions:
Addition or subtractions

Denominators must be the same
If they're different
then equivalent
fractions must be your aim

When you multiply
This rule does not apply
Don't you know divide is the same
Once you convert it

Mixed Numbers: change them before your calculation
Turn them into top heavy fractions instead

When you change them
Do the operation
On a piece of paper or in your head
If the answer that you get
Is top heavy don't forget
To change the fraction back to mixed

Converting fractions to decimals
On a calculator
All you have to do is to divide
The numerator by the denominator
You'll get a terminating decimal
Or else you'll find
It's really rather neat
That the numbers they repeat
Times by 100 then percent you will find

Cause when you're doing fractions:
Addition or subtractions

Denominators must be the same
If they're different
Then equivalent
Fractions must be your aim

When you multiply
This rule does not apply
Don't you know divide is the same
