Converting Fractions to Decimals

This video tutorial covers the first method of converting fractions to decimals by changing the denominator to a power of 10. It explains the importance of understanding place value and provides examples of converting fractions with denominators that are powers of 10, as well as those that are not. The video concludes with a note that if the denominator cannot be easily converted to a power of 10, long division will be necessary, which will be covered in part two.
