X=0,15*5/6-(0,7*3/7-4/5)/(1 1/2)

x=0,15*5/6-(7/10*3/7-8/10)/(3/2)
x=0.15*5/6-(3/10-8/10)/(3/2)
x=0,15*5/6-(-5/10*2/3)
x=15/100*5/6-(-1/3)

x= 1/8+1/3=3/24+8/24=11/24

y=(3 do potegi 4)do potegi -1*pierwiastek z 81*33
y=(3⁴)⁻¹*√81*33= 1/81*9 *33= 1/9*33=11/3=3 2/3

Procent z proporcji
11/24- 100 %
11/3- k

11/24*k= 11/3*100%/:24/11
k= 8*100%=800%
