Question

0,5×(1 целая 1/2 + 2 целых 2/3-1 целая 3/4)-1 целая 1/24

Answer 1

0.5=5/10=1/2
1 1/2=(2+1)/2=3/2
2 2/3=(6+2)/3=/8/3
1 3/4=(4+3)/4=7/4
1 1/24=(24+1)/24=25/24

1) 3/2+8/3=(3*3+8*2)/(2*3)=(9+16)/6=25/6
2)25/6-7/4=(25*2-7*3)/12=(50-21)/12=29/12
3)29/12*1/2=29/24
4)29/24-25/24=4/24=1/6
Ответ: 1/6
