Question

x : 0.25 + x : 0.5 + x + x :0.01 = 214

Answer 1

x:0.25=4x

x:0.5=2x

x:0.01=100x

=>4x+2x+x+100x=214

=>107x=214

=>x=2

Answer 2

x : 0.25 + x : 0.5 + x + x :0.01 = 214

x : ( 0,25 + 0,5 + 0,01 ) = 214

x : 0, 31 = 214

x= 214 x 0,31

x =66,34

Answer 3

<=>x.4+x.2+x+x.100=214

<=>x(4+2+1+100)=214

<=>x.107=214

<=>x=2 

vậy x=2
