Please explain what you do when asked to use compatible numbers.

Assistance needed.
Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well. 
I searched Google under the key words "compatible numbers math" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking. 
Are you sure that is 3rd grade? I am a 4th grader and I don't know any thing about it.
ps. When you are done with homework go to clubpegiun. It is really cool.
