Question

$45,09 \div 1,5 - (2 \times \frac{1}{3} - \times4 \times \frac{1}{2} - 2,5 \times 2 \times \frac{1}{2}) \div 4 \times \frac{1}{4} =$

Answer 1

$45.09 \div 1.5 - (2 \times \frac{1}{3} - 4 \times \frac{1}{2} - 2.5 \times 2$

$\times \frac{1}{2} ) \div 4 \times \frac{1}{4} .$

решаем в строчку :

$30 \frac{3}{50} - ( \frac{2}{3} - 2 - 2.5 \times 1) \div 4 \times \frac{1}{4} =$

$= 30 \frac{3}{50} - (( - 1 \frac{1}{3} ) - 2.5) \div 4 \times \frac{1}{4} =$

$= 30 \frac{3}{50} - ( - 3 \frac{5}{6}) \div 4 \times \frac{1}{4} =$

$= 30 \frac{3}{50} - ( - \frac{23}{74} ) \times \frac{1}{4} = 30 \frac{3}{50} - ( - \frac{23}{96} ) =$

$= 30 \frac{719}{2400} .$

$(30.299)$

Ответ :

$30 \frac{719}{2400} .$
