Ответ:
1. х = 1,25
2. х = 2,5
3. х = 0,625
4. х = 1,8
5. х = 6
6. х = 9,6
Пошаговое объяснение:
1. 5/6 = 2х/3 → 6*2х = 5*3 → 12х = 15 → х = 15/12 → х = 1,25
2. 4/9 = 8х/45 → 9*8х = 4*45 → 72х = 180 → х = 180/72 → х = 2,5
3. 5/12 = 2х/3 → 12*2х = 5*3 → 24х = 15 → х = 15/24 → х = 0,625
4. 6/7 = 10х/21 → 7*10х = 6*21 → 70х = 126 → х = 126/70 → х = 1,8
5. 8/9 = 4х/27 → 9*4х = 8*27 → 36х = 216 → х = 216/36 → х = 6
6. 27/5х = 9/16 → 5х*9 = 27*16 → 45х = 432 → х = 432/45 → х = 9,6
