√323.89 × (3.20) ÷ 9.02 =?
√323.89 × (3.20) ÷ 9.02 =? ≈ 18 × 3 ÷ 9 ≈ 6
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
√(24 × 5 ÷ ?) × 4 = 56 + 34 – 10
(60/15) × 25 + 15 2 – 18% of 200 = ? 2
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
64.5% of 800 + 36.4% of 1500 = (?)² + 38
(286 ÷ 11 + 14) × 5 = 40 + 25% of ?
38 – 3 2 + 5 2 + 6 2 = ? × 6
? = (25% of 20% of 800) × 8 – 25% of 260
√1369 + √1024 + √841 =(?)2 − 46
