## Operations with fractions

Posted by ricardogm on 24th September 2012

Hi

This is our first day in the computers room, so we have to do a lot of things:

1. Send me an email telling me your name, date of birth and if you hate or love maths, and why. You must use the same email adress all the year, of course.

2. Use wiris to correct the homework. The teacher is going to show you how.

3. Now it is time to use geogebra to understand operations with fractions. Go to this web, and then to this one. Try to solve exercises 6 and 7 and send me your answer.

4. Go to this web and read everything. Answer the questions in a word document (use copy and paste) and send it to me
