DIRECTIONS: Top-left to bottom-right, stepping only on fractions equal to
three quarters. No diagonals.
Divide top and bottom by the same number: 21/28 is 3/4. 22/29 will not divide.

Done for you 3/4 — already three quarters ✓ → 6/8 = 3/4 (both ÷ 2) ✓. 11/15 — nothing divides both ✗ not that way. Carry on from there.
- Write the fractions you stepped on, in order.
- Pick a cell you did not step on that looked tempting. Show the working that ruled it out.
- What do all the fractions on the route have in common when you look at the numbers themselves?
- Make up two more fractions that would be safe to step on, using numbers bigger than any on this board.
