Помагитееее срочноооооо !!!!!!!!! 30 баллов !!!!!!!!!!!!!

Answer 1

2 1/4, 2 1/2, 1 5/9, 2 7/10,

Answer 2

1. 2,25; 2,5; 1,5; 2,7; ~2,38; 2,13; 2,15; 4,23
2.
$\frac{7}{3} \frac{9}{2} \frac{29}{8} \frac{47}{9} \frac{31}{5} \frac{23}{3} \frac{39}{4} \frac{73}{6}$
3. 0,2 (1/5) 0,3 (3/10) 0,35 (7/20) 0,75 (3/4) 1,25 (1 1/4) 1,6 (1 3/5)
4.
$1) \: \frac{1}{5} + \frac{14}{25} = \frac{19}{25} = 0.76 \\ 2) \: \frac{7}{5} + 3 \times \frac{1}{2} = \frac{7}{5} + \frac{3}{2} = \frac{29}{10} = 2.9 \\ 3) \: \frac{55}{12} + \frac{13}{15} + \frac{3}{20} = \frac{28}{5} = 5 \times \frac{3}{5} = 5.6 \\ 4) \: \frac{16}{15} + \frac{21}{4} + \frac{1}{3} = \frac{133}{20} = 6 \times \frac{13}{20} = 6.65 \\ 5) \: \frac{3}{8} + \frac{35}{12} + \frac{15}{8} + \frac{1}{12} = \frac{21}{4} = 5 \times \frac{1}{4} = 5.25 \\ 6) \: 2 \times 2 + 5 \times \frac{5}{2} + \frac{9}{5} + 2 \times \frac{1}{3} = 4 + \frac{25}{2} + \frac{9}{5} + \frac{2}{3} = \frac{569}{30} = 18 \times \frac{29}{30} = 18.96$
5.
$7 \times \frac{5}{6} + 4 \times \frac{3}{4} + 3 \times \frac{5}{12} = \frac{35}{6} + 3 + \frac{5}{4} = \frac{121}{12} = 10 \times \frac{1}{12} = 10.083$
Ответ: Р =
$10 \times \frac{1}{12}$
