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 :

$30 frac{719}{2400} .$
