319.995 × 15.98 ÷ 4.002 - ? × 7.95 = 1679.89 ÷ 2.005
72.8% of (215.69 + 189.38) - 5.97² + (3.01 of 7.8) = ? of (64.02 - 38.95)
[√ (121.23)÷ √ (12100.04)]× √ 80.95 = 3/10 + ?÷ 4
...41.97 × 5.12 ÷ 2.99 + 49.89 = ?× 1.99
(124.99)² = ?
15.232 + 19.98% of 649.99 = ? × 4.99
(17.98% of 249.99) - 4.998 = √?
14.99 × ? + 19.91% of 359.74 = 62.62 × 4.03
?% of (742÷ 7.911) = (11.01)2
