найдите неизвестный член пропорции х : 6/7= 1целая 1/6 : 2целых 1/2 если что это дроби
х : 6/7= 1 1/6 : 2 1/2
x: 6/7 =7/6 :5/2
x=6/7 *7/6 :5/2
x=2/5
х:6/7 = 1 1/6:2 1/2
х= 6/7 * 1 1/6 = 2/5
2 1/2
6/7 * 1 1/6 = 6/7 * 7/6=1
1 : 2 1/2 = 1 : 5/2 = 1 * 2/5 = 2/5
Проверка:
2/5 : 6/7 = 7/6 : 5/2
2/5 * 5/2 = 7/6 * 6/7
1=1

2 1/2
6/7 * 1 1/6 = 6/7 * 7/6=1
1 : 2 1/2 = 1 : 5/2 = 1 * 2/5 = 2/5
Проверка:
2/5 : 6/7 = 7/6 : 5/2
2/5 * 5/2 = 7/6 * 6/7
