37% of 810 – 32% of 460.5 = ?
12 % of 72 × 25 – (x ÷ 20) × (16 ÷ 24) × 36 + 1/5 × x = (4 ÷ 12) × 36 ÷ 1/4
110 ÷ 5.5 + (?)3 ÷ 12 = 20(2/3)
5 × 14 + 100 ÷ 4 = 62 + ?
104 × 21 ÷ 13 + ? % of 300 = 320 + 22
(8.4 × 6.5 ×2.52 )/(5.04 ×3.25 ×2.1) = ?
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
20 + 160/? × 20 = 420
45% of 360 - 160 + ? = √324
