Answer 1

Ответ:

Пошаговое объяснение:

4÷2 2/5=4·5/12=5/3=1 2/3

5 5/7 ÷25=40/7 ·1/25=8/(7·5)=8/35

4 2/7 ÷5/7=30/7 ·7/5=6

6 2/3 ÷2 4/7=20/3 ·7/18=(10·7)/(3·9)=70/27=2 16/27

1 1/4 ÷1 2/3=5/4 ·3/5=3/4=0,75

Answer 2

Давайте посчитаем каждое из выражений по очереди:

1. 4:2 2/5 = ? Переведем смешанную дробь в неправильную дробь: 4:2 2/5 = 4 + 2/5 = 4 + 2 * (1/5) = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4 + 2/5 = 4
