б)2/15+7/12
в) 25/28-2/21

Answer 1

Ответ:

1/9+5/9=6/9=2/3

13/29-2/29=11/29

2/15+7/12=43/60

25/28-2/21=69/84

Answer 2

Ответ:

$\frac{1}{9} +\frac{5}{9} =\frac{6}{9}$

$\frac{13}{29} -\frac{2}{29}=\frac{11}{29}$

$\frac{2}{15} +\frac{7}{12} =\frac{8+35}{60} =\frac{43}{60}$

$\frac{25}{28} -\frac{2}{21} =\frac{150-16}{168} =\frac{134}{168}=\frac{67}{84}$
