Answer 1

$\mathsf{x=0,843777...\times1000}\\\mathsf{1000x=843,777...\times10}\\\mathsf{10000x=8437,777... }$

$-\underline{\begin{cases}\mathsf{10000x=8437,777...}\\\mathsf{1000x=843,777...}\end{cases}}$

$\mathsf{9000x=7594}\\\mathsf{x=\dfrac{7594\div2}{9000\div2}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{x=\dfrac{3797}{4500}}}}}}$
