64.5% of 800 + 36.4% of 1500 = (?)² + 38
12% of 152 + 12% of 150 = ? of 5
29% of 400 + 66% of 1100 - 50% of 1200 = ?
2/9 of 5/8 of 3/25 of ? = 40
34 × 2.5 + 6.4 × 1.5 – 4.8 × 1.2 =?
(25 + 12) x 6 + 34 = ? + 18
30% of 180 + 248 ÷ ? - √256 = 102
54 - 78 + 1518 + 1653 – 1252 = ?
(64/25)? × (125/512)?-1 = 5/8
125 + 64% of 250 = 150 + ?
