456 x 99.999 + 654 = ?
10.992 + (5.01 × 7.98) + ? = 361.03
(14.66)2 + (343.84 ÷ 3.88 - 55.87) = ? + 91.23
49.97% of 2016 – 37.99% of 1050 = ? – 47.98% of 5950
? = 44.78% of 839.91 – 48.12% of 774.89 + 55.77% of 1024.85
3.55% of 8120 – 66.66% of 540 = ? – 28% of 5500
? = 540.24 + 1022.97 – 11.992
9.95% of 1299.99 + 19.95 × 17.05 - 299.99 = ?
