Question

Решите пожалуйста, заранее спасибо!!!

Answer 1

а) x/2 + y/3 = 3x/6 + 2y/6 = 3x+2y/6

б) c/4 - d/12 = 3c/12 - d/12 = 3c-d/12

в) a/b - b²/a = a²/ab - b³/ab = a²-b³/ab

г) 3/2x - 2/3x = 9/6x - 4/6x = 9-4/6x = 5/6x

д) 5x/8y + x/4y = 5x/8y + 2x/8y = 7x/8y

е) 17y/24c - 25y/36c = 51y/72c - 50y/72c = y/72c

з) 3b/4c + c/2b = 3b²/4cb + 2c²/4cb = 3b²+2c²/4cb
