In order to Convert 3/11 into a decimal, you have to divide 3/11 out. If you were to put the three on top, and the 11 on the bottom, (here's a little tip to make it easier " top dog stays out and snoopy stays in. Top dog would be 3 because it is on the top of the fraction. Snoopy would be the 11 which is on the bottom of the fraction.) so with that being said..... So if you do 3 divided by 11 The answer would be 0.27272727...hope it helped.
