Question

1) 25,2:3+(6-414,6:2 (1-14-(5,76 - 316,5



помогите пожалуйста​

Answer 1

$25.2 \div 3 \frac{1}{2} + (6 - 4 \frac{1}{3} ) \times 0.6 = \frac{126}{5} \times \frac{1}{3} \times \frac{1}{2} \times (6 - \frac{13}{3} ) \times \frac{3}{5} = \frac{63}{5} \times \frac{5}{3} \times \frac{1}{5} = 63 \times \frac{1}{3} \times \frac{1}{5} = \frac{21}{5}$

$(7 - 1 \frac{5}{12} ) \div 6.7 + (5.75 - 3 \frac{1}{6} ) \div 15.5 = (7 - \frac{17}{12} ) \div \frac{67}{10} + ( \frac{23}{4} - \frac{19}{6} ) \div \frac{31}{2} = \frac{67}{12} \times \frac{10}{67} + \frac{31}{12} \times \frac{2}{31} = \frac{5}{6} + \frac{1}{6} = 1$
