Question

Вычислить ( 4 5/12-3 13/24): 1 3/4 + 1/6 по действиям!

Answer 1

$(4 \frac{5}{12} - 3 \frac{13}{24}) \div 1 \frac{3}{4} + \frac{1}{6}$

решаем по действиям :

$1)4 \frac{5}{12} - 3 \frac{13}{24} = \frac{53}{12} - \frac{85}{24} = \frac{106}{24} - \frac{85}{24} =$

$= \frac{21}{24} = \frac{7}{8} .$

$2) \frac{7}{8} \div 1 \frac{3}{4} = \frac{7}{8} \div \frac{7}{4} = \frac{7}{8} \times \frac{4}{7} = \frac{28}{56} = \frac{1}{2} .$

$3) \frac{1}{2} + \frac{1}{6} = \frac{3}{6} + \frac{1}{6} = \frac{4}{6} = \frac{2}{3} .$

Ответ :

$\frac{2}{3} .$

Answer 2

1. 4 5/12(×2)-3 13/24= 4 10/24 - 3 13/24= 3 34/24 - 3 13/24=21/24=7/8
2. 7/8÷1 3/4=7/8÷7/4=7/8×4/7=1/2
3. 1/2+1/6=1/2(×3)+1/6=3/6+1/6=4/6=2/3
