19. Simplify the following:(a) 75 = (3x 8 + 1) + 7 (5-3)(b) 3.9 - 1.3 -2.1 x 1.3 + 7.2 = 3.6(c) 3.06 = 3 x 3 - [0.8 + {6.5 – (5.5 = 1.1)}]

Answer»

75 ÷ (3 × 8 + 1) + 7 × (5 - 3) = 75 ÷ (25) + 14 = 173.9 ÷ 1.3 - 2.1 × 1.3 + 7.2 ÷ 3.6 = 3 - 2.73 + 2 = 2.273.06 ÷ 3 × 3 - [0.8 + {6.5 - (5.5 ÷ 1.1)}] = 1.02 × 3 - 2.3 = 0.76
