Decimals are dots that you put in the space for a number like 1.99.
a fraction is to see how many parts of a piece of pizza you have or any question like two over five.

Hi kuki87,

Fractions can be converted into decimals and they mean the same thing.  Some examples:
.25 is 1/4
.38 is 38/100
.50 is 1/2
.75 is 3/4
1.25 is 1 1/4
1.50 is 1 1/2 and so forth.

I've included a couple on links for you to explore, the first link is to an actual calculator, where you just type in the decimal form and it will convert the number into a fraction for you.  The second will explain how to convert fractions into decimals.  For example:
1.254 =1 + 2/10 + 5/100 + 4/1000 or 1/5 + 2/10 =.02

Hope this helps!

Very confusing topic. I found another website with some simple detail about Decimal to Fraction.
