Помогите пожалуйста!!! Номер 839
Б) 10/16 + 3/24 = 30/48 + 6/48 = 36/48 = 3/4 (или = 5/8 + 1/8 = 6/8 = 3/4), В) 30/45 + 8/36 = 120/180 + 40/180 = 160/180 = 8/9 (или = 2/3 + 2/9 = 6/9 + 2/9 = 8/9), Г) 60/120 + 75/150 = 1/2 + 1/2 = 2/2 = 1
10/16+3/24=(2*5)/(2*8)+3/(3*8)=5/8+1/8=6/8=(2*3)/(2*4)=3/4 30/45+8/36=(6*5)/(9*5)+(2*4)/(9*4)=6/9+2/9=8/9
