Question

x/100+0.99*x=0.5

 

Answer 1

\(\frac{x}{100}+0,99x=0,5\Rightarrow\frac{1}{100}x+\frac{99}{100}x=0,5\Rightarrow x=0,5\)

Answer 2

x : 100 + 0.99 . x = 0.5

x . \(\frac{1}{100}\) + 0.99 . x = 0.5

x . 0.01 + 0.99 . x = 0.5

x . ( 0.01 + 0.99 )  = 0.5

x . 1                     = 0.5

x                          = 0.5 : 1

x                          = 0.5

Answer 3

 Ta có x/100 + 0.99*x = 0.5

=> x. 1/100 + 99/100*x = 0.5

=> x*(1/100 + 99/100) = 0.5

=> x*1 = 0.5

=> x = 0.5

Nếu tìm x thì x=0.5 nhak bạn
