Пошаговое объяснение:

а)2/7=4/14  (умножили на 2)

б)40/80=20/40    (разделили на 2)

с)3/8=12/32   (умножили на 4)

д)50/125=2/5  (разделили на 25)

е)45/105=3/7    (разделили на 15

ф) 3/11=33/121   (умножили на 11)

имеется ввиду и числитель и знаменатель вместе умножают или разделяют на одно и тоже число


haiak76: Я не знаю почему но b пример сделан математичкой. И у неё выходит 2
gumbet: вместо знаменателя 2???
haiak76: Да
gumbet: извините, но так не правильно, потому что знам и числитель там сокращается на 2, а не в знаменателе получается 2, вы чтото сами не допоняли помоему
haiak76: Ладно, я ей скажу огромное спасибо!
medina325: спасибоооо
