сократите дроби 8*11/33*4,18*25/75*12/6*7+7*5/49

Сократите дроби

8*11/33*4,18*25/75*12/6*7+7*5/49 =
8/1 11/33 418/100 25/75 12/67 + 75/49=
сокращаем 11/33 на 11; 418/100 на 2; 25/75 на 25; 12/6 на 6; 7/49 на 7;

8/1 1/3 209/50 1/3 2/17+ 15/7=

8/3 209/50 2/37+ 5/7=

сокращаем 50 и 2 на 2

8/3 209/25 1/37+ 5/7=
(8209)/(32537)+ 5/7=

(8209)/(32537)+
(53253)/(73253)=

1672/1575+ 1125/1575=

1 97/1575+ 1125/1575=

1 1222/1575.


Если там 4/18

8*11/33*4/18*25/75*12/6*7+7*5/49 =

8/1 11/33 4/18 25/75 12/67 + 75/49=
(Уменьшаем 11/33 на 11; 4/18 на 2; 25/75 на 25; 12и 6 на 6; 7 и 49 на 7)

8/1 1/3 2/9 1/3 2/17+ 15/7=

32/567+ 5/7= 32/567+ (581)/(781)=

32/567+ 405/567= 437/567
