1) =1/2+1/8=4/8+1/8=5/8
2) = 1-1/18=18/18-1/18=17/18
Пошаговое объяснение:
1)1/2+(1/4)/2=4/8+1/8=5/8
1-(1/6)/3=18/18-1/18=17/18
2)1/2+1/(4/2)=1/2+1/2=1
1-1/(6/3)=3/3-1/3=2/3
1) =1/2+1/8=4/8+1/8=5/8
2) = 1-1/18=18/18-1/18=17/18
Пошаговое объяснение:
1)1/2+(1/4)/2=4/8+1/8=5/8
1-(1/6)/3=18/18-1/18=17/18
2)1/2+1/(4/2)=1/2+1/2=1
1-1/(6/3)=3/3-1/3=2/3
