Помогите пожалуйста!!!

Answer 1

$(20.88 \div 18 + 45 \div 0.36) \div (19.59 + 11.95) = (1.16 + 125) \div 31.54 = 126.16 \div 31.54 = 4$

$\frac{7}{36} \times 9 + 8 \times \frac{11}{32} + \frac{9}{10} \times \frac{5}{18} = \frac{7}{4} + \frac{11}{4} + \frac{1}{4} = \frac{19}{4} = 4 \frac{3}{4} = 4.75$

$(3 \frac{4}{25} + 0.24) \times 2.15 + (5.1625 - 2 \frac{3}{16}) \times \frac{2}{5} = 3.4 \times 2.15 + 2.975 \times 0.4 = 7.31 + 1.19 = 8.5$

$0.364 \div \frac{7}{25} + \frac{5}{16} \div 0.125 + 2 \frac{1}{2} \times 0.8 = 1.3 + 2.5 + 2 = 5.8$
