To solve a math problem for homework Carrie needed to find the total of 2 3/4 6.00 and 3 4/5 What should Carrie have gotten as an answer?
7.55?

Ms. Sue,
I got a much different answer.

Ms. Sue,
If you rounded the numbers with fractions, you'd get 13.

Jerald,
Oh because what I did was divide 3/4 and I got .75 and then I divided 4/5 and got 80. Then I added 6.00 .75 and .80 and got 7.55. But then I didn't know what to do with the whole number. So how do you figure out you were suppose to round?

Math 
Ms. Sue,
I used the rounding example as a way of showing how far off your answer is.
2.75 + 6 + 3.8 = ?
