Question

(0,75-0,25*4,2):0,2(45)+1|3

Answer 1

$1) \: 0.25 \times 4.2 = 1.05 \\ 2) \: 0.75 - 1.05 = - 0.3 \\ 3) \: - 0.3 \div 0.2 = - 1.5 \\ 4) \: - 1.5 \times 45 = - 67.5 \\ 5) \: 67.5 + \frac{1}{3} = \frac{ - 135}{2} + \frac{1}{3} = \frac{ - 405}{6} + \frac{2}{6} = \frac{ - 403}{6} = - 67 \times \frac{1}{6}$
