Converting Between Fractions and Terminating Decimals
Fraction into a decimal
- To convert a fraction into a decimal divide the numerator by the denominator.
- You may need to use long division and use a recurring symbol if needed.
Terminating decimal to fraction
- To convert a terminating (not recurring) decimal into a fraction:
- Put the number after the decimal point on top and a power of ten on the bottom with as many zeros as there were decimal places.
- Remember to cancel down fractions if possible.
