Factor both the numerator and denominator, and then divide both the numerator and denominator by the greatest common factor.

For example, 1/3 + 1/6 = 2/6 + 1/6 = 3/6. We have to simplify 3/6. The factors of 3 are 3 and 1. The factors of 6 and 1, 2, 3, and 6. The greatest common factor is 3. Dividing the numerator and denominator by 3 results in 1/2.

Good luck.

I have had TI connect for quite a while, and recently I started having the same issue. I'm running Windows 7. I was able to get it to work by forcing it to run in compatibility mode.

In the window that pops up, click the "Compatibility" tab, select the checkbox that says "Run this program in compatibility mode for", and select "Windows XP (Service Pack 3)" in the box below. Click OK and try to connect again.

Hope it helps.
