Practice 8Quick check
What is \(\frac{1}{4} + \frac{1}{6}\)?
\(\frac{3}{12} + \frac{2}{12} = \frac{5}{12}\). Adding tops and bottoms (\(\frac{2}{10}\)) is the classic mistake.
Practice 9Quick check
What is \(3 - \frac{1}{5}\)?
Write \(3\) as \(2\frac{5}{5}\), then subtract \(\frac{1}{5}\).
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
