$$7/ 9$$
$$7/ 9 = (7 / 9 \times 2 / 2) = (7 / 9 \times 3 / 3) = (7 / 9 \times 4 / 4) = (7 / 9 \times 5 / 5) = (7 / 9 \times 6 / 6)$$
$$\therefore 7 / 9 = 14 / 18 = 21 / 27 = 28 / 36 = 35 / 45 = 42 / 54$$
The five fractions are $$14 / 18, 21 / 27, 28 / 36, 35 / 45$$ and $$42 / 54$$
Hence, the five fractions equivalent to $$7 / 9$$ are $$14 / 18, 21 / 27, 28 / 36, 35 / 45$$ and $$42 / 54$$
