A bag contains 18 black and 20 white balls. One ball is drawn at random. What is the probability that the ball drawn is white?
(2/7)% of 5600 ÷ √ 64 = ?
2916 ÷ 54 = ? + 27
4387897 – 3286871 – 51926 = ?
12% of 10% of 15% of 5000 + (12 x 15) = ?
3? x 23 ÷ √ 256 = 40.5
(64/25)? × (125/512)?-1 = 5/8
16 × ? + 36% of 250 = 410
√(82 × 7 × 52 - 175) = ?
7/3 of 4/5 of 15/56 of ? = 83
240 × 2.5 + 65 × 2/13 = ?2 - √225
