Hi Israell, There are some different ways that you can think about changing 1/4 to a decimal. 1. Think of 1/4 as "one divided by four" and when you either put that into a calculator or do long division, you'll get .25. When you put that with the 3, you'll have 3.25. 2. The "whole" for a decimal is 1.00, right? (or you can think of that as a dollar, $1.00.) If you have a "quarter" of a dollar, it's 25 cents, so you'll get 1/4 equal to .25 thinking this way, too. Either way 3 and 1/4 equals 3.25. I hope that helps! Our Ask Dr. Math pages might help next time you have a question. You can start browsing here: http://mathforum.org/dr.math/ Suzanne
