Question

помогите пожалуйста это срочно​

Answer 1

Ответ:

$\frac{5}{6} + \frac{3}{8} = \frac{20 + 9}{24 } = \frac{29}{24} = 1 \frac{5}{24}</p><p>[tex] \frac{19}{21} - \frac{11}{15} = \frac{95 - 77}{105} = \frac{18}{105} = \frac{6}{35}$

$\frac{21}{22} - \frac{3}{55} = \frac{105 - 6}{110} = \frac{99}{110} = \frac{9}{10} = 0.9$

$\frac{5}{42} + \frac{10}{63} = \frac{15 + 20}{126} = \frac{35}{126} = \frac{5}{18}$

$\frac{11}{21 } - \frac{2}{35} = \frac{55 - 6}{105} = \frac{49}{105} = \frac{7}{15}$

$\frac{5}{24} + \frac{7}{60} = \frac{25 + 14}{120} = \frac{39}{120} = \frac{13}{40 }$

Answer 2

Ответ:

ж) 5/6+3/8=20/24+9/24=29/24=1 5/24

з)19/21-11/15= 95 /105- 77/105=18/105=6/35

и) 21/22-3/55=105/110-6/110=99/110=9/10

к)5/42+10/63=15/126+20/126=35/126=5/18

л) 11/21-2/35=55/105-6/105=49/105=7/15

м)5/24+7/60=25/120+14/120=39/120=13/40
