Решите пропорцию x:2/3=3:4. x:6=1/3:8. 12:29=1/58:x. 144:125=1 1/2:x.

Х: 2/3 = 3 : 4 х: 6 = 1/3 : 8

х * 4 = 2/3 * 3 х * 8 = 6 * 1/3

х * 4 = 2 х * 8 = 2

х = 2 : 4 х = 2 : 8

х = 1/2 х = 1/4

12 : 29 = 1/58 : х 144 : 125 = 1 цел 1/2 : х

12 * х = 29 * 1/58 144 : 125 = 3/2 : х

12 * х = 29/58 144 * х = 125 * 3/2

12 * х = 1/2 144 * х = 375/2

х = 1/2 : 12 х = 375/2 : 144

х = 1/2 * 1/12 х = 375/2 * 1/144

х = 1/24 х = 375/288 = 125/96

х = 1 цел 29/96
