For the first stage, we can round up or down the decimals to nearest unit.

Cattle: 440 – 490 = -50
Percentage change = (50 ÷ 490) x 100 ≈ 10%

Pigs: 70 – 90 = -20
Percentage change = (20 ÷ 90) x 100 ≈ 20%

Potatoes: 117 – 81 = 36
Percentage change = (36 ÷ 81) x 100 ≈ 50%

Wool: 7.4 – 7.7 = -0.3
Percentage change = (0.3 ÷ 7.7) x 100 ≈ 4%

Vegetables: 38.3 – 34.5 = 3.8 = 4
Percentage change = (4 ÷ 34) x 100 ≈ 12.5%

So the biggest percentage change is seen in potatoes.
