$$90 × 6 = 540$$
$$900 × 6 = 5400$$
$$9000 × 6 = 54000$$
$$810 ∶ 9 = 90$$
$$8100 ∶ 9 = 900$$
$$81000 ∶ 9 = 9000$$
$$140 - 9 × 5 = 140 - 45 = 95$$
$$150 - 7 × 8 = 150 - 56 = 94$$
$$160 - 8 × 8 = 160 - 64 = 96$$
$$88 ∶ 22 × 10 = 4 × 10 = 40$$
$$77 ∶ 11 × 100 = 7 × 100 = 700$$
$$96 ∶ 32 × 1000 = 3 × 1000 = 3000$$
