Question

3/4-(×+1/20)=1/5 помогите решить

Answer 1

3/4-(×+1/20)=1/5
x+1/20=3/4-1/5
x+1/20=11/20
x=11/20-1/20
x=1/2
Ответ:1/2.

Answer 2

$frac{3}{4} -(x+ frac{1}{20}) = frac{1}{5}$
$x+ frac{1}{20} = frac{3}{4} -frac{1}{5} = frac{11}{20}$
$x=frac{11}{20}-frac{1}{20}= frac{10}{20} = frac{1}{2} =0.5$
