Converting Fractions to Decimals

Today in class we learned about converting fractions to decimals. You do this by dividing the numerator by the denominator.For example 4/5 is equal to .80. This is because 4 divided by 5 is 0.8 so that is the decimal. Sometthing a little more complicated is say -4 and 7 tenths is -4.7 because 4 is the whole number so thats where you get the 4 and 7 tenths is just the same as 0.7.

We also learned about about how to convert decimals to fractions; in their simplest form. All you have to do is 0.25=25/100=25/100 divided by 25 = 1/4. when doing this you always want to right the fraction in simplest form.

Also you can do 0.625=625/1000=625/1000 divided by 25 is 25/40 which divided by 5 is 5/8.
