Step-by-step explanation:
For converting from fraction to decimal, simply divide the top by the bottom.
For converting from decimal to fraction, depending on how many places there are, you choose what to divide by. Ex: .002 (there are 3 places, it is divided by 1,000)
For fraction to percent, you divide the top by the bottom, make it a decimal, and move the decimal over two places to the RIGHT.
For percent to decimal, you move the decimal over two places to the LEFT.
