44 • 1/33. 2.1/3 : 3.1/2
------------- : ---------------------------- = 1/225
5 : 1/2. 15 : 5/8 • 3.1/8 • 1.3/5
Решение первого столбика:
1) 44 • 1/33 = 44/1 • 1/33 = 44/33 = 4/3 = 1.1/3
2) 5 : 1/2 = 5/1 : 1/2 = 5/1 • 2/1 = 5/2 = 2.1/2
3) 1.1/3 : 2.1/2 = 4/3 : 5/2 = 4/3 • 2/5 = 8/15
Решение второго столбика:
1) 2.1/3 : 3.1/2 = 7/3 : 7/2 = 7/3 • 2/7 = 1/3 • 2/1 = =2/3
2) 15 : 5/8 = 15/1 : 5/8 = 15/1 • 8/5 = 3/1 • 8/1 = =24/1 = 24
3) 24 • 3.1/8 = 24/1 • 25/8 = 3/1 • 25/1 = 75/1 = 75
4) 75 • 1.3/5 = 75/1 • 8/5 = 15/1 • 8/1 = 125/1 = 125
Первый столбец = 8/15
Второй столбец = 125
8/15 : 125 = 8/15 : 125/1 = 8/15 • 1/125 = 1/15 • 1/15 = 1/225
