Question

Скажите сколько будет плис

Answer 1

1) 3 11/27-2 17/18=3 22/54-2 51/54=25/54

25/54:1 23/27=25/54*27/50=1/4

3 3/5:3=18/5*1/3=18/15=1 1/5

1/4+1 1/5=5/20+1 4/20=1 9/20

2) 2 4/15-1 5/12=2 16/60-1 25/60=51/60

51/60:3 2/5=51/60*5/17=3/12=1/4

6 4/9:2=58/9*1/2=58/18=3 2/9

1/4+3 2/9=9/36+3 8/36=3 17/36

Answer 2

$(3 \frac{11}{27} - 2 \frac{17}{18} ) \div 1 \frac{23}{27} + 3 \frac{3}{5} \div 3 = ( \frac{92}{27} - \frac{53}{18} ) \div \frac{50}{27} + \frac{18}{5} \div 3 \\ \frac{184 - 159}{54} = \frac{25}{27} \div \frac{50}{27} + \frac{18}{5} \div \frac{3}{1} = \frac{25}{27} \times \frac{27}{50} + \frac{18}{5} \times \frac{1}{3} = \frac{1}{2} + \frac{6}{5} = \frac{5 + 12}{10} = \frac{17}{10} = 1 \frac{7}{10}$
$\frac{51}{60} \times \frac{5}{17} + \frac{58}{9} \times \frac{1}{2} = \frac{3}{12} + \frac{29}{9} = \frac{9 + 116}{36} = \frac{125}{36} = 3 \frac{17}{36}$
