We obtain turmeric from which part of the plant?

(39.933% of 30.03) - (27.78 `xx` 15.30) = ? - (40 `xx` 38.87)

(1680.23 ÷ 27.98) + (600.32 ÷ 23.9) + 1384.11 = ?

14.74² ÷ 24.98 × 15.76 = ?% of 359.88

(79.79% of 800.24 - √224.75) × (2/5 of 499.71) ÷ (10% of 600.26) = ?

20.22% of (61.9 × 5.01) + 69.97 =?
