Answer 1

104. найдем оба числа. потом разделим х на z м умножим на 100%

х=(25*135)/(3*100)-0.25=11.25-0.25=11;

z=(108-106.75)*88/5=1.25*88/5=1.28*88/5=22

11*100%/22=50%

2) х=(1/3)*(40  12/21-38  7/21)*(7/19)= (1/3)*(2 5/21  )*(7/19)=47/(9*19)

z=0.6*20/27=12/27=4/9

47*9*100%/(9*19*4)=47*25%/19=(61   16/19)%

105. 1) (81/37)*(73 4/18-71 3/18)=(81/37)*(37/18)=9/2

5*9/2=45/2

(9/2)*(2/45)*100%=20%

2) ( 8 1/2+9 2/3)*(60/109)=(109*60)/(6*109)=10

(24 7/15+4/5)*(300/379)=379*300/(15*379)=20

10*100%/20=50%
