(3333 ÷30) + (785 ÷25) + (2981 ÷11) = ?
8 × 12 + 110 ÷ 5 = 72 + ?
(0.1 × 0.2 × 0.3) + (0.3 × 0.4 × 0.5) =?
?/343 = 7/?
3.3 Times 2/27 of 40% of 364=?
(25)² × 4 ÷ 5 + (3)³ + 48=? + 425
666(2/3)% of 30 - 116(2/3)% of 90 =?
16 × ? + 36% of 250 = 410
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
`(450 -: ?)/(2.5 xx 1.2)` = 250
