Key idea: Rationals on the number line
Every rational has a unique location on the number line. To plot p/q:
- If q > 0 and p > 0, count p/q units to the right of 0.
- If p < 0, count to the left.
- For 5/4, divide each unit between 1 and 2 into 4 equal parts and pick the first one past 1.
Unlike integers (which leave gaps between consecutive values), rationals appear infinitely close to each other on the number line.
- If q > 0 and p > 0, count p/q units to the right of 0.
- If p < 0, count to the left.
