do you mean "how to add mixed numbers with decimals"becoz u cant add mixed numbers using decimals!
I'm going to go with what rosala said about adding mixed numbers and decimals to answer this question.
It would depends if you want your answer in decimals or in fraction form.
It is alot easier to turn the mixed number into a decimal and then add the two decimals together.
Let's say we had 2 ¾ + 0.333333
We can divide 3 by 4 to get 0.75.
Since 2 is a whole number, we have 2.75.
2.75 + 0.333333 = 3.083333
There, that's how we add the two numbers if we want to have our answer in decimal form.
If you want to turn the decimal to a fraction then add to get your answer in a fraction form, it's more difficult...but still possible.
CPhill has a method on how to do this. Scroll down to the 6th reply of this post to read about it.
But the question is something else NinjaDevo!and to find it look at the posts again!
Yeah, I see rosala.
I noticed that right after I posted it, so I just edited my original post.
Thanks for the reminder though. :)
